fix: propagate baseUrl correctly in API key authentication (#446)

Fix bug where baseUrl was not properly propagated through the
authentication chain, causing remote deployments to fall back
to localhost:3003 instead of using the actual deployment URL.

Changes:
- Update extractContextFromApiKey to accept and pass baseUrl parameter
- Update all calls to extractContextFromApiKey to pass baseUrl from request
- Improve error logging in A2AClient to show actual error details

This ensures A2A agent card fetches use the correct deployment URL
in production environments.
