fix(lint): resolve pre-existing lint errors and merge conflicts

- Remove unused imports/vars from routes.ts (VALID_TRANSITIONS, AUTOMATION_PRESETS, ChatStore, FileListResponse, etc.)
- Prefix unused destructured error vars with _ convention
- Fix prefer-const for summary variable
- Add _ ignore pattern to eslint.config.mjs
- Include test files in tsconfig.app.json to fix @testing-library/jest-dom types
- Resolve GitManagerModal.test.tsx merge conflict (take fn-1626 expectLatestCallStartsWith style)
