Subject: [PATCH] Add request tracing, debug /v1/keys/list endpoint

- TraceLayer logs every HTTP request (method, path, status, duration)
- Default log level info, tower_http=debug (no RUST_LOG needed)
- GET /v1/keys/list shows all registered fingerprints
- Helps debug key registration and lookup issues
