fix(web): stop reporting "no update" when the update check could not run

check-update returned update_available=False whenever git failed. The banner
is the only route to the update button, so a checkout git refuses to touch
looked exactly like a current one -- permanently, with nothing on screen to
act on and only a log line recording why.

The common cause is an install performed as root. scripts/install/one-shot-install.sh
clones into ${HOME}/LEDMatrix, never consults SUDO_USER, and contains no chown
at all, while its own error text suggests running the whole thing under sudo.
The result is a root-owned checkout, and on a rig this is what every git
command in it does:

    fatal: detected dubious ownership in repository at '...'

including the fetch this endpoint runs. Verified on real hardware rather than
assumed.

A failed check now reports check_failed with a message the user can act on --
for dubious ownership, the chown that fixes it. The banner shows that message
instead of hiding itself, with the update button suppressed since updating
cannot work until the cause is fixed. The success path is untouched.

This does not fix the installer, which is the real cause; it stops the symptom
being invisible. The installer needs SUDO_USER handling and a chown, and its
suggestion to run as root should go.

Reverting the endpoint change fails four of the five new tests; the fifth
guards the success path and correctly does not move.

+"""A checkbox group must not post back options it cannot show.
+
+The enum that lets the widget draw checkboxes is also what validates the
+saved value. When a league retires a team code -- OAK for the Athletics, ARI
+for the Coyotes -- or a schema drops an option, a config that still holds the
+old value has nothing to render for it. The value stayed in the hidden
+``_data`` input regardless, because that input is seeded from the stored array
+and only rebuilt by ``updateCheckboxGroupData()`` on change. Editing any other
+field on that plugin therefore posted the stale value back, the schema
+rejected it, and the save endpoint returned 400
+``CONFIG_VALIDATION_FAILED`` -- so the whole plugin became uneditable until
+the user worked out which invisible entry was at fault.
+
+Runtime was never affected: plugin loading treats schema violations as
+warn/degrade, and the stale code already matched no team. Only the web UI
+blocked.
