peter 921c2bf5a4 test(db): harden the DB lane per code-review (R6 S3)
/code-review high on S3 — 3 low findings, 2 fixed, 1 no-change:
- _db_reachable() now probes via a throwaway engine with connect_timeout=3, so a
  slow/firewalled DATABASE_URL can't hang the whole suite at import (the app engine
  has no connect timeout).
- test_plex_facets sets the "configured" gate flag via monkeypatch (auto-restored)
  instead of poking state._configured_cache in a manual finally — no leak risk, and
  the now-unnecessary mark_configured DB write is dropped.
No change: test_plex_jsonb_normalize copying migration 0060's SQL is deliberate —
migrations must stay self-contained (no app imports) and a shipped migration is
immutable, so there's no real drift to guard against.

Gate: ruff clean; DB lane 176 passed; pure-logic 172 passed / 4 skipped (fast).

"""DB-backed regression for the 0.53.1 hotfix (R6 S3b-test): GET /api/plex/facets?scope=show
must return 200 — not the "cannot extract elements from a scalar" 500 — for a metadata-poor
library whose show has a JSONB-scalar `null` genres (a pre-0.53.1 row). The endpoint's
`jsonb_typeof(genres)='array'` read-guard is what makes it safe; this test would 500 without it.
Uses the DB lane (`db` fixture) — skipped when no Postgres is reachable.
