- Move ajax.php to controllers/ajax.php for better file organization
- Update require path and add conditional loading check in ajax.php
- Add ajax.php to legacy routes array in web.php
- Change route methods from GET to ANY for legacy controllers to support all HTTP methods
- Update root route to support all HTTP methods as well
