Tests: add email-gating API coverage; robust task-uncancel seeding; re-quarantine flaky onboarding e2e

- Issue 2 (coverage gap): add HoneyDueAPITests/AuthGatingAPITests — verifies the
  backend's RequireVerified gate (unverified -> 403, verified -> 200) at the API
  layer, since UI-test mode bypasses verification. NOTE: surfaced that the gate
  is applied to only the share-code routes, not residence/task routes — unverified
  users are NOT broadly blocked (flagged for product/backend).
- Issue 4: TaskCRUDUITests seedAccountPreconditions now guarantees a residence
  (no silent early-return), so the cancelled-task precondition always populates;
  XCTUnwrap replaces the misleading "not seeded" skip. The two uncancel tests now
  skip with the ACCURATE reason: cancelled tasks are intentionally hidden from the
  Tasks Kanban and the iOS Tasks view has no "show cancelled" surface (product gap).
- Issue 3: re-quarantine testF110 after a hardening attempt — the register->verify
  transition is irreducibly flaky; coverage is redundant with OnboardingTaskCache
  + the F-series. Skip reason is now precise, with a TODO to stabilize the handoff.
