Fix post-registration navigation and add comprehensive registration UI tests

- Fix RegisterView to call AuthenticationManager.login() after email verification
  so user is properly transitioned to home screen instead of returning to login
- Fix ResidencesListView to load data when authentication state becomes true,
  ensuring residences load after registration/login
- Add accessibility identifier to verification code field for UI testing
- Add NSAppTransportSecurity exceptions for localhost/127.0.0.1 for local dev
- Add comprehensive XCUITest suite for registration flow including:
  - Form validation tests (empty fields, invalid email, mismatched passwords)
  - Full registration and verification flow test
  - Logout from verification screen test
  - Helper scripts for test user cleanup
