feat: Implement Phase 1.5 entity models (Park, Ride, Company, RideModel, Photo)
- Created Company model with location tracking, date precision, and CloudFlare Images - Created RideModel model for manufacturer's ride models with specifications - Created Park model with location, dates, operator, and cached statistics - Created Ride model with comprehensive stats, manufacturer, and park relationship - Created Photo model with CloudFlare Images integration and generic relations - Added lifecycle hooks for auto-slug generation and count updates - Created migrations and applied to database - Registered all models in Django admin with detailed fieldsets - Fixed admin autocomplete_fields to use raw_id_fields where needed - All models inherit from VersionedModel for automatic version tracking - Models include date precision tracking for opening/closing dates - Added comprehensive indexes for query performance Phase 1.5 complete - Entity models ready for API development
