test: add ChatService unit tests, fix DockerService TS error, add .env.test

- Create chat_service.spec.ts with tests for suggestion parsing (comma/newline
  separated, bullet points, numbered lists, quote stripping), model selection
  (largest model), error handling for all DB-dependent methods, generateTitle
  fallback logic, and message role validation
- Fix TypeScript narrowing error in docker_service.spec.ts container command
  splitting test (null type cast)
- Add .env.test with required environment variables for test suite bootstrap
