fix: remove unused imports and fix logger test isolation

- Remove unused imports (run, trackDuration, PerformanceTracker,
  ConfigManager, disconnectDb) flagged by ESLint
- Remove unused isSlow variable in performance-monitor catch block
- Add eslint-disable for require() in Playwright JS script
- Fix logger-performance test flakiness by using vi.resetModules()
  with dynamic imports to prevent cached logger references across
  test files
