Fix skipped tests and improve testing infrastructure (#22)

- Install missing ts-jest dependency to fix Jest configuration
- Enhance renderTestApp with UI mode support for help, archived, diff views
- Create comprehensive test data factories with builder pattern
- Enable all 11 previously skipped E2E tests for navigation and data flow
- Refactor tests to use self-documenting Given/When/Then structure
- Add proper TypeScript typing for all test data models

All 72 tests now pass with no skipped tests. Testing infrastructure
significantly improved for future development.
