test: Add comprehensive Playwright E2E tests and TDD unit tests

- Add navigation E2E tests (responsive, 404 handling, accessibility)
- Add CRUD user management E2E tests with POM pattern
- Add email validation unit tests with TDD (20 tests, 100% passing)
- Add password strength validation with TDD (23 tests, 100% passing)
- Demonstrate Red-Green-Refactor cycle in practice
- All tests follow parameterized testing best practices
