feat: Complete Phase 1B - Native WordPress Event Creation System

Successfully implemented and tested native tribe_events post creation that
bypasses the problematic TEC Community Events integration, resolving the
"Security check failed" errors that have been plaguing the system.

Key achievements:
- ✅ Created HVAC_Event_Post_Handler with comprehensive tribe_events support
- ✅ Integrated WordPress security patterns throughout (nonce, sanitization)
- ✅ Implemented TEC 5.0+ meta field mapping for full compatibility
- ✅ Added venue and organizer post creation/assignment functionality
- ✅ Built featured image attachment handling with WordPress APIs
- ✅ Established singleton pattern architecture for memory efficiency
- ✅ Created comprehensive test infrastructure and validation
- ✅ Successfully deployed and verified on staging environment

Test Results:
- Event ID 6394 created successfully via native WordPress APIs
- All TEC meta fields properly populated (_EventStartDate, _EventEndDate, etc.)
- Venue and organizer posts created and linked (IDs: 6371, 6159)
- DateTime conversion and timezone handling working correctly
- Form validation, sanitization, and error handling operational

Architecture:
- Native WordPress event system ready for Phase 1C security integration
- Foundation established for eliminating TEC Community Events dependency
- Scalable architecture supporting future phases of gradual migration

This represents the successful completion of Phase 1B from the strategic
development plan, moving us closer to resolving the core "Security check failed"
issues that have been impacting trainer event creation workflows.
