Pin forgectrl 0.1.22 (the releases-API check and the release dialog) and cover its routes

forgectrl 0.1.22 = 0235a88: the release check reads the GitHub releases
API and never requests the firmware file's URL, the daemon checks daily,
and the panel raises a per-release dismissable alert and runs the install
from one dialog.

Acceptance: update.release-check (auto) exercises GET /update/release,
POST /update/check (a machine with no route to the API answers 502, which
the drill records and steps over), the v<semver> shape and `new` of a
published release, and the dismissal round trip, and puts the dismissal
back. forgectrl.auth's unauthenticated-write list gains /update/check and
/update/dismiss. Coverage lint: 84 tests, 0 uncovered paths; the
forgetest unit tests pass (373). On the bench reference (dev image
20260911203113 with forgectrl 0.1.22 hot-deployed) every check of both
tests passed; the runs were marked FAIL only by the hand-back baseline,
because the controller is gated until the changed privacy advisory is
accepted again.
