This implementation provides automatic geocoding and map integration:
- **Event Model Enhancements:**
- Automatic geocoding callback using OpenStreetMap Nominatim API
- 3-tier fallback system: exact coordinates → city-based → country default
- Fallback coordinates for major French cities (Paris, Lyon, Marseille, etc.)
- Robust error handling that prevents event creation failures
- **User-Friendly Event Forms:**
- Address-first approach - users just enter addresses
- Hidden coordinate fields (auto-generated behind scenes)
- Real-time geocoding with 1.5s debounce
- "Ma position" button for current location with reverse geocoding
- "Prévisualiser" button to show map links
- Smart feedback system (loading, success, warnings, errors)
- **Enhanced Event Show Page:**
- Map provider links (OpenStreetMap, Google Maps, Apple Plans)
- Warning badges when approximate coordinates are used
- Address-based URLs for better map integration
- **Comprehensive JavaScript Controller:**
- Debounced auto-geocoding to minimize API calls
- Multiple geocoding strategies (manual vs automatic)
- Promise-based geolocation with proper error handling
- Dynamic map link generation with address + coordinates
- **Failure Handling:**
- Events never fail to save due to missing coordinates
- Fallback to city-based coordinates when exact geocoding fails
- User-friendly warnings when approximate locations are used
- Maintains existing coordinates on update failures
