refactor: use endpoint_id instead of endpoint name for routing

- Update route_payload to use endpoint_id instead of endpoint name
- Update AuthData to expect endpoint_id (int) instead of endpoint (str)
- Update ClientState to track endpoint_id
- Update comfyui client functions to use endpoint_id
- Fetch endpoint info (id + api_key) instead of just api_key

This aligns with the autoscaler changes in AUTO-848 that switched
to ID-based endpoint lookups for improved security and consistency.
