feat(api): require api_key when binding to all interfaces (parity with WS gateway)
The OpenAI-compatible API server had no authentication option, unlike the
WebSocket gateway which already refuses wildcard binds without a token.
When bound to 0.0.0.0, any caller who could reach the port could drive
the agent with its default tool posture.
- Add api_key field to ApiConfig (schema.py).
- Add wildcard_host_requires_auth validator that rejects wildcard binds
without api_key, mirroring the WS gateway pattern.
- Add Bearer-token auth middleware to the API server (server.py).
/health remains unauthenticated.
- Replace the wildcard-host CLI warning with a hard error when api_key
is unset, and pass api_key to create_app.
Fixes#4490
