Add pytest tests for forwarder and retro endpoints

- Added test cases for the `/nx/forwarder/{console}/{tid}` and `/nx/retro/{tid}` endpoints to validate retro forwarder functionality.
- Included a new forwarder TID for the 3DS console in the test database to ensure accurate testing.
- Enhanced test coverage to verify correct responses and error handling for forwarders and unsupported platforms.
