Fix ruff and ESLint warnings in tests and tsconfig

- Wrap long dict literal in test_geo_service.py across multiple lines (E501)
- Combine nested with statements in test_jail_service.py (SIM117)
- Add vitest.config.ts to tsconfig.node.json include so ESLint
  parserOptions.project resolves it correctly
