Add comprehensive UI test suite with XCUITest

Added complete UI test suite covering authentication, residences, tasks,
and contractors. Tests follow best practices with helper methods, proper
waits, and accessibility identifier usage.

New test files:
- UITestHelpers.swift: Shared helper methods for login, navigation, waits
- AuthenticationTests.swift: Login, registration, logout flow tests
- ComprehensiveResidenceTests.swift: Full residence CRUD and validation tests
- ComprehensiveTaskTests.swift: Task creation, editing, completion tests
- ComprehensiveContractorTests.swift: Contractor management and edge case tests
- ResidenceTests.swift: Additional residence-specific scenarios
- TaskTests.swift: Additional task scenarios
- SimpleLoginTest.swift: Basic smoke test for CI/CD
- MyCribUITests.swift: Base test class setup
- AccessibilityIdentifiers.swift: Test target copy of identifiers

Test coverage:
- Authentication: Login, registration, logout, error handling
- Residences: Create, edit, delete, validation, multi-field scenarios
- Tasks: Create, complete, edit, cancel, status changes
- Contractors: Create with minimal/full data, phone formats, specialties

All tests use accessibility identifiers for reliable element location and
include proper waits for asynchronous operations.
