UI test infrastructure overhaul — 58% to 96% pass rate (231/241)

Major infrastructure changes:
- BaseUITestCase: per-suite app termination via class setUp() prevents
  stale state when parallel clones share simulators
- relaunchBetweenTests override for suites that modify login/onboarding state
- focusAndType: dedicated SecureTextField path handles iOS strong password
  autofill suggestions (Choose My Own Password / Not Now dialogs)
- LoginScreenObject: tapSignUp/tapForgotPassword use scrollIntoView for
  offscreen buttons instead of simple swipeUp
- Removed all coordinate taps from ForgotPasswordScreen, VerifyResetCodeScreen,
  ResetPasswordScreen (Rule 3 compliance)
- Removed all usleep calls from screen objects (Rule 14 compliance)

App fixes exposed by tests:
- ContractorsListView: added onDismiss to sheet for list refresh after save
- AllTasksView: added Task.RefreshButton accessibility identifier
- AccessibilityIdentifiers: added Task.refreshButton
- DocumentsWarrantiesView: onDismiss handler for document list refresh
- Various form views: textContentType, submitLabel, onSubmit for keyboard flow

Test fixes:
- PasswordResetTests: handle auto-login after reset (app skips success screen)
- AuthenticatedUITestCase: refreshTasks() helper for kanban toolbar button
- All pre-login suites use relaunchBetweenTests for test independence
- Deleted dead code: AuthenticatedTestCase, SeededTestData, SeedTests,
  CleanupTests, old Suite0/2/3, Suite1_RegistrationRebuildTests

10 remaining failures: 5 iOS strong password autofill (simulator env),
3 pull-to-refresh gesture on empty lists, 2 feature coverage edge cases.
