feat: Integrate navigation and breadcrumbs into all trainer templates

- Created template integration class for automatic nav/breadcrumb injection
- Added trainer-header.php template part for consistent header
- Updated all trainer page templates to include navigation and breadcrumbs
- Navigation shows hierarchical menu with dropdowns
- Breadcrumbs provide context-aware navigation trail

All trainer pages now have consistent navigation structure
