Add comprehensive iOS unit and UI test suites for greenfield test plan

- Create unit tests: DataLayerTests (27 tests for DATA-001–007), DataManagerExtendedTests
  (20 tests for TASK-005, TASK-012, TCOMP-003, THEME-001, QA-002), plus ValidationHelpers,
  TaskMetrics, StringExtensions, DoubleExtensions, DateUtils, DocumentHelpers, ErrorMessageParser
- Create UI tests: AuthenticationTests, PasswordResetTests, OnboardingTests, TaskIntegration,
  ContractorIntegration, ResidenceIntegration, DocumentIntegration, DataLayer, Stability
- Add UI test framework: AuthenticatedTestCase, ScreenObjects, TestFlows, TestAccountManager,
  TestAccountAPIClient, TestDataCleaner, TestDataSeeder
- Add accessibility identifiers to password reset views for UI test support
- Add greenfield test plan CSVs and update automated column for 27 test IDs
- All 297 unit tests pass across 60 suites
