Two CI bounces on b65e956:
1. ruff UP017 — Python 3.14's preferred form is `datetime.UTC`, not
`timezone.utc`. Switch the test's two TZ literals.
2. test_directory_card_shape pinned the card key set to the pre-feature
shape; `unseen_count` was added to the API payload but the pin
wasn't updated. Same shape as the recurring 'plan-grep-pinned-tests'
trap — should have grepped tests/ for card.keys() before pushing.
Removed the app/client fixtures duplicated across 36 test files (two
variants: separate app + client(app), and a self-contained client() that
called create_app inline) and the now-unused create_app imports. Both
fixtures now live once in conftest.py. test_suggestions_bulk keeps its
import (builds the app inline in two tests); test_health drops its local
client + unused pytest_asyncio.
Net -415 lines.
