Build-gate fix for the v4.11.12 timezone flip — no user-facing change.

Notes from the Archivist

v4.11.13 = CI-gate hotfix for v4.11.12 (#130). Enabling ruff DTZ in v4.11.12 was verified against app/ tests/ alembic/ but CI runs `ruff check .` over the WHOLE repo and flagged a naive datetime literal in scripts/validate_cutover.py:190 (a cutover-probe INSERT sentinel), failing the lint gate — so v4.11.12 built NO image and never deployed (prod stayed v4.11.11). Fix: updated_at=datetime(2026, 1, 1) -> datetime(2026, 1, 1, tzinfo=UTC). No app-code, model, or migration change; the whole #130 flip rides in v4.11.12's records. Lesson: the DTZ enablement should have been validated with `ruff check .` (CI's scope), not a path subset.
