Add test utilities and state machine diagrams for FSM models

- Introduced reusable test utilities in `backend/tests/utils` for FSM transitions, HTMX interactions, and common scenarios.
- Added factory functions for creating test submissions, parks, rides, and photo submissions.
- Implemented assertion helpers for verifying state changes, toast notifications, and transition logs.
- Created comprehensive state machine diagrams for all FSM-enabled models in `docs/STATE_DIAGRAMS.md`, detailing states, transitions, and guard conditions.

+
+## Loading States
+
+- [ ] Loading spinner/indicator appears immediately on button click
+- [ ] Button becomes disabled during transition
+- [ ] Spinner disappears when response received
+- [ ] Multiple rapid clicks don't cause duplicate requests
+
+## Confirmation Dialogs
+
+- [ ] Dialog appears for dangerous transitions (reject, cancel, demolish)
+- [ ] Dialog shows appropriate warning message
+- [ ] Clicking "Cancel" prevents transition
+- [ ] Clicking "OK/Confirm" executes transition
+- [ ] ESC key dismisses dialog without action
+- [ ] Dialog backdrop click dismisses without action
+
+## Cross-Browser Testing
+
+Test all scenarios above in each browser:
+
+### Desktop
+
+- [ ] Chrome/Chromium (latest)
+- [ ] Firefox (latest)
+- [ ] Safari/WebKit (latest)
+- [ ] Edge (latest)
+
+### Mobile
+
+- [ ] Mobile Safari (iOS 15+)
+- [ ] Chrome Mobile (Android)
+- [ ] Samsung Internet (Android)
+
+### Notes
+
+- Test with different viewport sizes (mobile, tablet, desktop)
+- Verify touch interactions work on mobile
+- Check that modals/dialogs are properly positioned on mobile
+
+## Accessibility
+
+### Keyboard Navigation
+
+- [ ] All transition buttons focusable via Tab key
+- [ ] Enter key activates focused button
+- [ ] Escape key closes confirmation dialogs
+- [ ] Focus indicator visible on all interactive elements
+- [ ] Focus returns to appropriate element after transition
+
+### Screen Reader
+
+- [ ] Status changes announced to screen readers
+- [ ] Toast notifications announced (aria-live region)
+- [ ] Button labels are descriptive
+- [ ] Loading states communicated to screen readers
+
+### Visual
+
+- [ ] Color contrast meets WCAG AA standards
+- [ ] Status colors distinguishable without relying solely on color
+- [ ] Focus indicators have sufficient contrast
+- [ ] Text remains readable at 200% zoom
+
+## Performance
+
+- [ ] Transitions complete in under 500ms (typical)
+- [ ] No visible flickering during HTMX swap
+- [ ] Memory usage stable after multiple transitions
+- [ ] No console errors during normal operation
+
+## Test Data Reset
+
+After testing, reset test data:
+```bash
+uv run manage.py flush_test_data
+uv run manage.py loaddata test_data
+```
+
+## Reporting Issues
+
+When reporting issues:
+1. Note browser and version
+2. Include console errors (if any)
+3. Describe expected vs actual behavior
+4. Include network request/response details
+5. Screenshot or video if possible
+
+## Automated Testing
+
+Run automated E2E tests to complement manual testing:
+
+```bash
+# Run all FSM E2E tests
+pytest backend/tests/e2e/test_moderation_fsm.py
+pytest backend/tests/e2e/test_park_ride_fsm.py
+pytest backend/tests/e2e/test_fsm_permissions.py
+pytest backend/tests/e2e/test_fsm_error_handling.py
+
+# Run with specific browser
+pytest --browser firefox backend/tests/e2e/
+
+# Run with headed mode (visible browser)
+pytest --headed backend/tests/e2e/
+
+# Run integration tests (faster, no browser)
+pytest backend/tests/integration/test_fsm_transition_view.py

+## FSM State Machine Integration with HTMX
+
+### Overview
+The codebase implements a reusable FSM (Finite State Machine) infrastructure using django-fsm, integrated with HTMX for seamless state transitions without full page reloads.
+
+### Core Components
+
+1. **FSMTransitionView** (`apps/core/views/views.py`)
+   - Generic view for handling FSM state transitions via HTMX POST requests
+   - Validates permissions using `can_proceed` from django-fsm
+   - Executes transitions and returns updated HTML partials
+   - Sends HX-Trigger headers for toast notifications
+
+2. **FSM Template Tags** (`apps/core/templatetags/fsm_tags.py`)
+   - `get_available_transitions`: Returns available transitions for an object/user
+   - `get_state_value`: Gets current state value
+   - `get_state_display`: Gets human-readable state display
+   - `default_target_id`: Generates HTMX target IDs
+   - `app_label`, `model_name`: Model metadata filters
+
+3. **Reusable Partials** (`templates/htmx/`)
+   - `status_with_actions.html`: Combined status badge with action buttons
+   - `state_actions.html`: Standalone action buttons
+   - `updated_row.html`: Generic fallback for row updates
+
+### Integration Pattern
+
+```django
+{% load fsm_tags %}
+
+<!-- Include FSM status and actions -->
+{% include 'htmx/status_with_actions.html' with object=submission user=user show_badge=True %}
+```
+
+### FSM Transition Flow with HTMX
+
+```mermaid
+sequenceDiagram
+    participant User
+    participant Browser
+    participant HTMX
+    participant FSMTransitionView
+    participant Model
+    participant Template
+
+    User->>Browser: Click "Approve" button
+    Browser->>HTMX: hx-post to FSM transition URL
+    HTMX->>FSMTransitionView: POST /moderation/submissions/<pk>/transition/transition_to_approved/
+    FSMTransitionView->>FSMTransitionView: Validate permissions (can_proceed)
+    FSMTransitionView->>Model: Execute transition
+    Model->>Model: Update status field + save
+    Model-->>FSMTransitionView: Return updated object
+    FSMTransitionView->>Template: Render model-specific partial
+    FSMTransitionView-->>HTMX: HTTP 200 + HX-Trigger: showToast
+    HTMX->>Browser: Swap target element with new HTML
+    HTMX->>Browser: Trigger showToast event
+    Browser->>User: Display updated row + success toast
+```
+
+### URL Pattern Configuration
+
+FSM transitions use a consistent URL pattern:
+```
+/api/moderation/<model_plural>/<pk>/transition/<transition_name>/
+```
+
+Example URL patterns in `apps/moderation/urls.py`:
+```python
+path(
+    "submissions/<int:pk>/transition/<str:transition_name>/",
+    FSMTransitionView.as_view(),
+    {"app_label": "moderation", "model_name": "editsubmission"},
+    name="submission_transition",
+)
+```
+
+### Template Resolution
+
+FSMTransitionView automatically resolves model-specific templates:
+1. `{app_label}/partials/{model_name}_row.html`
+2. `{app_label}/partials/{model_name}_item.html`
+3. `{app_label}/partials/{model_name}.html`
+4. `htmx/updated_row.html` (fallback)
+
+### Toast Notifications
+
+The FSMTransitionView includes HX-Trigger headers for toast notifications:
+```python
+response["HX-Trigger"] = json.dumps({
+    "showToast": {
+        "message": "Submission approved successfully",
+        "type": "success"
+    }
+})
+```
+
+Dashboard templates listen for these events with Alpine.js:
+```javascript
+@show-toast.window="showToast($event.detail)"
+```
+
+### Status Badge Styling
+
+The `status_with_actions.html` partial includes automatic styling based on state:
+- `PENDING` - Yellow (warning)
+- `APPROVED` - Green (success)
+- `REJECTED` - Red (danger)
+- `ESCALATED` - Orange (caution)
+- `IN_PROGRESS` - Blue (info)
+
+### Flash Animations
+
+Successful transitions include a flash animation class:
+```css
+.animate-flash-success {
+    animation: flash-success 1s ease-in-out;
+}
+```
+
+### Error Handling Flow

+
+### Testing FSM HTMX Transitions
+
+#### Unit Tests
+Backend unit tests in `apps/moderation/tests.py`, `apps/parks/tests.py`, and `apps/rides/tests.py` cover:
+- FSM transition logic and state changes
+- Permission guards and role-based access
+- Transition history logging with django-fsm-log
+- Callback execution and side effects
+
+#### Integration Tests
+Integration tests in `backend/tests/integration/test_fsm_transition_view.py` verify:
+- FSMTransitionView handles HTMX requests correctly
+- HX-Trigger headers contain proper toast data
+- Correct partial templates rendered for each model
+- Permission validation before transition execution
+- StateLog entries created for each transition
+
+#### E2E Tests
+End-to-end tests using Playwright in `backend/tests/e2e/` validate:
+- Complete user interaction flow from button click to UI update
+- Toast notifications appear and auto-dismiss
+- Loading indicators show during transitions
+- Error handling displays user-friendly messages
+- Permission guards prevent unauthorized transitions
+- Cross-browser compatibility (Chrome, Firefox, Safari)
+
+Test files:
+- `test_moderation_fsm.py` - EditSubmission, PhotoSubmission transitions
+- `test_park_ride_fsm.py` - Park and Ride status changes
+- `test_fsm_permissions.py` - Permission guard verification
+- `test_fsm_error_handling.py` - Error scenarios and loading states
+
+#### Running Tests
+```bash
+# Run all FSM tests
+pytest -k fsm
+
+# Run e2e FSM tests
+pytest backend/tests/e2e/test_moderation_fsm.py

+
+### States
+
+| State | Color | Description |
+|-------|-------|-------------|
+| OPERATING | Green | Ride is open and operating |
+| UNDER_CONSTRUCTION | Blue | Ride is being built |

+| CLOSED_PERM | Red | Permanently closed |
+| DEMOLISHED | Gray | Ride has been removed |
+| RELOCATED | Gray | Ride has moved to new park |
+
+### Special: CLOSING Status
+
+The CLOSING status has special behavior:
+- When a ride enters CLOSING, a `closing_date` should be set
+- When the closing date passes, `apply_post_closing_status()` is called
+- The ride transitions to the `post_closing_status` (default: CLOSED_PERM)
+- This allows announcing closures ahead of time

+```
+
+### States
+
+| State | Color | Description |
+|-------|-------|-------------|
+| PENDING | Yellow | Scheduled, waiting to start |
+| RUNNING | Blue | Currently processing |
+| COMPLETED | Green | Finished successfully |
+| FAILED | Red | Encountered error |
+| CANCELLED | Gray | Manually cancelled |
+
+---
+
+## Common Patterns
+
+### Permission Guards
+
+All transitions include permission guards:
+
+```python
+@transition(
+    field=status,
+    source='PENDING',
+    target='APPROVED',
+    permission='apps.moderation.can_approve_submission'
+)
+def transition_to_approved(self, user=None):
+    pass
+```
+
+### Confirmation Requirements
+
+Dangerous transitions require confirmation in the UI:
+
+- Reject (any submission)
+- Cancel (any operation)
+- Close Permanently (park/ride)
+- Demolish (park/ride)
+
+### Toast Notifications
+
+All transitions trigger toast notifications:
+
+| Transition Type | Toast Color | Icon |
+|-----------------|-------------|------|
+| Approve | Green | check |
+| Reject | Red | times |
+| Escalate | Orange | arrow-up |
+| Complete | Green | check-circle |
+| Cancel | Red | ban |
+
+---
+
+## Testing Transitions
+
+See the test documentation:
+
+- **Unit tests**: `backend/apps/*/tests.py`
+- **Integration tests**: `backend/tests/integration/test_fsm_transition_view.py`
+- **E2E tests**: `backend/tests/e2e/test_*_fsm.py`
+- **Manual testing**: `backend/tests/e2e/BROWSER_TESTING_CHECKLIST.md`
+
+---
+
+## Implementation Notes
+
+### Adding New Transitions
+
+1. Add the transition method to the model with `@transition` decorator
+2. Define source states, target state, and permission guard
+3. Update the template to show the new button
+4. Add tests for the new transition
+5. Update this documentation
+
+### State Field Configuration
+
+States are defined using `RichFSMField` which integrates with:
+- django-fsm for transition logic
+- django-fsm-log for transition history
+- RichChoices for metadata (colors, icons, labels)
+
+```python
+status = RichFSMField(
+    choice_group="statuses",
+    domain="moderation",
+    max_length=20,
+    default="PENDING"
+)
+```
