Move config.js script to head section so it loads synchronously before
any module scripts execute. This fixes a race condition on mobile where
the app could initialize before window.CONFIG was set.

Completed HIGH severity security fix (CVSS 6.5) to prevent Google Maps
API key exposure to frontend clients.
Issue: API key was embedded in photo URLs sent to frontend, allowing
potential abuse and quota exhaustion.
Solution: Implemented backend proxy endpoint for photos.
Backend Changes:
- google-maps.client.ts: Changed photoUrl to photoReference, added fetchPhoto()
- stations.types.ts: Updated type definition (photoUrl → photoReference)
- stations.controller.ts: Added getStationPhoto() proxy method
- stations.routes.ts: Added GET /api/stations/photo/:reference route
- stations.service.ts: Updated to use photoReference
- stations.repository.ts: Updated database queries and mappings
- admin controllers/services: Updated for consistency
- Created migration 003 to rename photo_url column
Frontend Changes:
- stations.types.ts: Updated type definition (photoUrl → photoReference)
- photo-utils.ts: NEW - Helper to generate proxy URLs
- StationCard.tsx: Use photoReference with helper function
Tests & Docs:
- Updated mock data to use photoReference
- Updated test expectations for proxy URLs
- Updated API.md and TESTING.md documentation
Database Migration:
- 003_rename_photo_url_to_photo_reference.sql: Renames column in station_cache
Security Benefits:
- API key never sent to frontend
- All photo requests proxied through authenticated endpoint
- Photos cached for 24 hours (Cache-Control header)
- No client-side API key exposure
