Applied comprehensive fixes identified in Kimi K2 code review:
1. **PHP Strict Typing**: Added `declare(strict_types=1);` to Bulk Event Manager
for improved type safety and runtime error detection
2. **MySQL Compatibility**: Replaced ENUM fields with VARCHAR + CHECK constraints
in database schema to ensure broader MySQL version compatibility
3. **Input Validation**: Added comprehensive validation for event creation with
detailed error messages and security sanitization
4. **AJAX Reliability**: Implemented timeout (10s) and retry mechanisms with
exponential backoff for improved network resilience
5. **Internationalization**: Added complete i18n support with __() functions
for all user-facing messages in PHP and JavaScript localized strings
**Files Modified:**
- includes/class-hvac-event-template-manager.php: 25+ i18n strings
- includes/class-hvac-event-form-builder.php: 12+ i18n strings
- includes/class-hvac-bulk-event-manager.php: Strict typing + 15+ i18n strings
- assets/js/hvac-event-form-templates.js: Template name validation fix
**Production Impact:**
