This change implements a failover strategy for API keys to handle rate limiting (HTTP 429).
It introduces a MultiKeyIDFMApi wrapper that accepts a list of API keys (comma-separated in config).
When a 429 error is encountered during authenticated API calls (get_traffic, etc.), the wrapper automatically rotates to the next available key and retries.
The project dependency is updated to a specific git branch of idfm-api that exposes the RequestError exception with status codes.
Unauthenticated calls (get_lines, get_stops) remain unchanged as they do not use the API key.


PR created automatically by Jules for task 11574969537721125545 started by @azman0101

- Update `manifest.json` to use forked `idfm-api` with `RequestError` support.
- Implement `MultiKeyIDFMApi` wrapper to handle key rotation on 429 errors.
- Update `config_flow.py` and `__init__.py` to support comma-separated keys and use the wrapper.
- Ensure `get_traffic`, `get_destinations`, `get_directions`, `get_line_reports` support failover.
- Keep `get_lines` and `get_stops` as pass-through (Open Data, no key needed).
