Implements /find-training page with Google Maps JavaScript API:
- Interactive map showing trainers (teal) and venues (orange) markers
- MarkerClusterer for dense areas
- Filter by State, Certification, Training Format
- Search by name/location
- "Near Me" geolocation with proximity filtering
- Trainer profile modal with contact form
- Venue info modal with upcoming events
- 301 redirect from /find-a-trainer to /find-training
- Auto-geocoding for new TEC venues via Google API
Multi-model code review fixes (GPT-5, Gemini 3, Zen MCP):
- Added missing contact form AJAX handler with rate limiting
- Fixed XSS risk in InfoWindow (DOM creation vs inline onclick)
- Added caching for filter dropdown queries (1-hour TTL)
- Added AJAX abort handling to prevent race conditions
- Replaced alert() with inline error notifications
