Show desktop update check feedback (#1808)

* fix(desktop): show app update check feedback

Manual desktop app update checks now leave visible status feedback even when the shared update state is pending or available. Updater check and preparation errors are carried through the existing result path so the settings row and callout can show the failure instead of only logging it.

* fix(desktop): make update retries perform fresh checks

Manual retries now clear runtime errors emitted by a failed check so the next click calls the updater again. Background checks also skip while a visible manual check is active, and last-checked update copy uses complete localized strings.

* fix(desktop): punctuate update check timestamp copy

* fix(desktop): share runtime update errors

* fix(desktop): preserve update preparation errors

* fix(desktop): settle update check review races

* fix(desktop): settle quiet update check errors

* fix(desktop): handle overlapping update checks

* fix(desktop): preserve preparation errors during checks
