Matysh c749b52a0d v1.45.1: follow-up review of v1.45.0 — R3-1, R3-2
R3-1 (high): v1.45.0 made the upload safe but left deletion to the client —
after a successful save the card asked the backend to remove everything but the
file it had just committed. Two open editors cannot be ordered: a delayed
request from one deleted the plan the other had just saved, leaving the
accepted configuration pointing at nothing, the exact damage copy-on-write was
introduced to prevent.

houseplan/plan/cleanup is removed. config/set collects inside its own write
lock from the two configurations that bracket the commit (plans.collect_plans):
a file the old revision referenced and the new one does not is superseded and
goes; any other unreferenced upload waits out PLAN_ORPHAN_TTL_S, because a
fresh one may belong to a transaction that has not committed yet. The collector
lives in a pure module so it can be reasoned about and unit-tested without the
HA harness.

R3-2: houseplan-space-card signed its plan url and threw the result away —
getCardSize() mutated a throwaway model while render() rebuilt its own from the
config, so the <image> requested the protected path and got 401 on every
render. Both cards now share ContentSigner (src/signing.ts), which also gives
the static card batching, expiry handling and periodic re-signing.  is
released in finally: one failed request no longer wedges a url for the life of
the page.

Tests: five backend interleaving cases from the report, six unit tests for the
pure collector, smoke_space_card_bg (verified to fail against a v1.45.0 build:
the raw url reaches the DOM and no retry happens). 57 smokes, 124 unit, 22
backend-pure.
