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 Co-authored-by: johndoe6345789 <224850594+johndoe6345789@users.noreply.github.com>
