feat(find-training): New Google Maps page replacing buggy MapGeo implementation

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

+**Last Updated:** February 1, 2026

-## 🎯 CURRENT SESSION - MULTI-MODEL SECURITY CODE REVIEW (Jan 31, 2026)
+## 🎯 CURRENT SESSION - FIND TRAINING PAGE IMPLEMENTATION (Jan 31 - Feb 1, 2026)
 
 ### Status: ✅ **COMPLETE - Ready for Staging Deployment & E2E Testing**
 
-**Objective:** Comprehensive security and business logic code review using 4 AI models (GPT-5, Gemini 3, Kimi K2.5, Zen MCP) across 11 critical files (~9,000 lines).
+**Objective:** Replace the buggy MapGeo-based `/find-a-trainer` page with a new `/find-training` page built from scratch using Google Maps JavaScript API.
 
-### Review Methodology
+### Why This Change
-- **Phase 1:** Security review with GPT-5, Gemini 3, Kimi K2.5 (parallel)
+The existing IGM/amCharts implementation had a fundamental bug that corrupted marker coordinates (longitude gets overwritten with latitude). After multiple fix attempts, building fresh with Google Maps API provides:
-- **Phase 2:** Business logic review with GPT-5, Gemini 3, Kimi K2.5 (parallel)
+- Full control over marker data
-- **Phase 3:** Zen OWASP audit, Architecture analysis, Code review synthesis (parallel)
+- No third-party plugin dependencies
-- **Phase 4:** Consolidated findings report with consensus-based prioritization
+- Better long-term maintainability
+- Ability to show both trainers AND venues

+## 📋 PREVIOUS SESSION - E2E TESTING & BUG FIXES (Feb 1, 2026)
+
+### Status: ✅ **COMPLETE - Deployed to Staging, Ready for Production**
+
+**Objective:** Deploy security fixes to staging, run E2E tests, fix discovered bugs, and validate all functionality.
+
+### Deployment & Testing Summary
+
+1. ✅ **Deployed to Staging** - All 12 security fixes from previous session
+2. ✅ **E2E Tests Passed** - Master trainer pages, security endpoints verified
+3. ✅ **Discovered & Fixed 2 Critical Bugs** - Trainers table, event pages
+4. ✅ **Created E2E Testing Skill** - `.claude/commands/e2e-visual-test.md`
+5. ✅ **Added Staging Email Filter** - Prevents accidental user spam
+
+### Bugs Found & Fixed
+
+| Bug | Severity | Root Cause | Fix |
+|-----|----------|------------|-----|
+| **Trainers table empty** | HIGH | `ajax_filter_trainers()` used complex SQL that returned empty; `count_trainers_by_status()` only queried `hvac_trainer` role | Rewrote to use `get_trainers_table_data()` (same as working dashboard); fixed role query to include both roles |
+| **Event pages blank** | HIGH | Template path mismatch: code referenced `page-trainer-event-manage.php` but file is `page-manage-event.php` | Fixed path in `class-hvac-event-manager.php:138` |
+
+### Files Modified (4 files)
+
+1. **`includes/class-hvac-master-trainers-overview.php`**
+   - Rewrote `ajax_filter_trainers()` to use reliable `get_trainers_table_data()`
+   - Fixed `count_trainers_by_status()` to include `hvac_master_trainer` role
+   - Now shows 53 trainers, 5 active (was showing 0)
+
+2. **`includes/class-hvac-event-manager.php`**
+   - Fixed template path: `page-trainer-event-manage.php` → `page-manage-event.php`
+   - Event creation form now fully functional
+
+3. **`hvac-community-events.php`**
+   - Added staging email filter (only `ben@tealmaker.com` receives emails)
+   - Protects real users from test emails during development
+
+4. **`.claude/commands/e2e-visual-test.md`** (new)
+   - Created E2E visual testing skill for Playwright MCP browser tools
+   - Documents login procedure, test sequence, credentials
+
+### E2E Test Results
+
+| Feature | Status | Notes |
+|---------|--------|-------|
+| Master Trainer Login | ✅ PASS | Custom `/training-login/` works |
+| Master Dashboard | ✅ PASS | Stats, tables, AJAX functional |
+| Trainers Table | ✅ PASS | 53 trainers displayed correctly |
+| Announcements | ✅ PASS | Modal opens, form accessible |
+| Event Creation | ✅ PASS | Full form with all TEC fields |
+| Certificate Reports | ✅ PASS | Empty state (needs events) |
+| Security Endpoints | ✅ PASS | 4/4 properly return 401/400 |
+
+### Staging Email Protection
+
+Emails on staging are now filtered:
+- **Allowed:** `ben@tealmaker.com`, `ben@measurequick.com`
+- **Blocked:** All other recipients (logged for debugging)
+- **Subject Prefix:** `[STAGING]` added to allowed emails
+
+### Next Steps
+1. ⏳ Deploy to production: `./scripts/deploy.sh production`
+2. ⏳ Verify production functionality
+3. ⏳ Monitor for any issues
