Pull request overview
This pull request refactors JWT token generation for model service endpoints by centralizing the logic in the Circuit model and reducing token payload size. The changes move JWT creation from the endpoint API to a new model method while removing unnecessary and sensitive data from the token payload.
- Centralized JWT generation logic in a new
Circuit.generate_jwtmethod - Reduced JWT payload size by removing
configandroute_infofields - Removed direct
jwtlibrary usage from the endpoint API

resolves #7704 (BA-3668).
This pull request focuses on reducing the size of JWT tokens generated for model service endpoints by removing unnecessary information and centralizing the logic for JWT creation. The changes streamline the payload, mask sensitive data, and move JWT generation to the
Circuitmodel for better maintainability.JWT Generation Improvements:
generate_jwtmethod to theCircuitmodel to create JWT tokens with only essential information, removing unrelated and sensitive fields such asconfigandroute_info. (src/ai/backend/appproxy/coordinator/models/circuit.py, src/ai/backend/appproxy/coordinator/models/circuit.pyR417-R431)generate_jwtmethod, ensuring a smaller and cleaner JWT payload. (src/ai/backend/appproxy/coordinator/api/endpoint.py, src/ai/backend/appproxy/coordinator/api/endpoint.pyL303-R304)Codebase Cleanup:
jwtlibrary from the endpoint API, consolidating JWT logic in the model layer. (src/ai/backend/appproxy/coordinator/api/endpoint.py, src/ai/backend/appproxy/coordinator/api/endpoint.pyL9)jwtimport to the model file to support the new centralized JWT generation method. (src/ai/backend/appproxy/coordinator/models/circuit.py, src/ai/backend/appproxy/coordinator/models/circuit.pyR5)Documentation:
