feat: Complete Phase 5 of Django Unicorn refactoring for park detail templates
- Refactored park detail template from HTMX/Alpine.js to Django Unicorn component
- Achieved ~97% reduction in template complexity
- Created ParkDetailView component with optimized data loading and reactive features
- Developed a responsive reactive template for park details
- Implemented server-side state management and reactive event handlers
- Enhanced performance with optimized database queries and loading states
- Comprehensive error handling and user experience improvements
docs: Update Django Unicorn refactoring plan with completed components and phases
- Documented installation and configuration of Django Unicorn
- Detailed completed work on park search component and refactoring strategy
- Outlined planned refactoring phases for future components
- Provided examples of component structure and usage
feat: Implement parks rides endpoint with comprehensive features
- Developed API endpoint GET /api/v1/parks/{park_slug}/rides/ for paginated ride listings
- Included filtering capabilities for categories and statuses
- Optimized database queries with select_related and prefetch_related
- Implemented serializer for comprehensive ride data output
- Added complete API documentation for frontend integration
