fix: CI lint errors and formatting

- Fix 5 react-hooks/set-state-in-effect lint errors:
  - AgentActivityLog: use useRef instead of useState for previous value tracking
  - FileTree: restructure fetch effect with cancellation pattern
  - SettingsPanel: lazy useState initializer from localStorage
  - useWalkthrough: lazy useState initializer from localStorage
  - TicketGenerationProgress: eslint-disable for intentional reset pattern
- Run ruff format on all 157 backend files
- Add gitpython to requirements for type generation CI job
