- Removed hardcoded `driver-class-name` from `application.yaml` to enable Spring Boot's driver auto-detection, fixing the startup failure in production where H2 driver was being used with a PostgreSQL URL.
- Updated `ApiExceptionHandler` to handle `NoResourceFoundException`, ensuring that unmapped paths (like `/`) return a 404 Not Found response instead of a 500 Internal Server Error.
- Added `NotFoundControllerTest` to verify the fix.
