feat: add security event taxonomy and optimize park queryset
- Add comprehensive security_event_types ChoiceGroup with categories for authentication, MFA, password, account, session, and API key events
- Include severity levels, icons, and CSS classes for each event type
- Fix park queryset optimization by using select_related for OneToOne location relationship
- Remove location property fields (latitude/longitude) from values() call as they are not actual DB columns
- Add proper location fields (city, state, country) to values() for map display
This change enhances security event tracking capabilities and resolves a queryset optimization issue where property decorators were incorrectly used in values() queries.
- Add new /profiles/ endpoint for listing user profiles
- Support search by username/display name with ordering options
- Include pagination with configurable page size (max 100)
- Add comprehensive OpenAPI schema documentation
- Refactor passkey authentication state management in MFA flow
- Update URL routing and imports for new list_profiles view
This enables user discovery, leaderboards, and friend-finding features
with a publicly accessible, well-documented API endpoint.
