Reorganize event processors and update routing

- Move process_event.php from src/admin to src/processors
- Move toggle_event_published.php from src/admin to src/processors
- Move delete_event.php from src/admin to src/processors
- Update .htaccess rewrite rules to point event processors to correct location
- Keep admin_events.php and manage_events.php in admin (display pages only)

src/processors/delete_event.php
