feat(a11y): add focus lock dependency and useDialogFocus hook

- Install react-focus-lock@2.13.7 for focus trap functionality - Create useDialogFocus hook with focus management, Escape key handling, initial focus, focus restoration, and body scroll lock - Create E2E test infrastructure with helper functions for focus testing - Compatible with React 19 and Electron 39
