peter 351eb5fd13 test(plex)+cleanup(quota): S2 code-review fixes (R6 S2)
/code-review high on S2 — 4 findings, 2 fixed, 2 no-change:
- test_plex_sync_txn: a faked PlexClient fails on the second library; asserts the
  first library's row survives (per-section commit). Mutation-checked — moving the
  commit back out of the loop turns it red ([] == ['1']).
- dropped the `[[quota-owns-its-session]]` memory slugs from quota.py docstrings
  (a dangling private-note reference in shipped code; the reasoning is already inline).
No change: record_usage's per-call second connection is a transient spike, fine for
this app's concurrency; the two-site `with SessionLocal()` duplication isn't worth a
helper until a third caller appears.

Gate: ruff clean; DB lane 181 green.

"""DB-backed test for R6 S2's Plex per-section commit: a PlexError on a LATER library must keep the
libraries already mirrored (committed per section), not roll the whole reconcile back. Uses the DB
lane (`db` fixture) with a faked PlexClient — skipped without Postgres.
