#388 feat(updates): choose how often to check, and show release notes

[Anonymous]

Originally created by: kristofferR

Automatic update checks ran on a fixed four-hour schedule, and the update prompt only said that a new version existed, not what changed, before asking for consent to install.

Check frequency. Settings → Advanced gains Check for updates: every hour, every 4 hours (default) or once a day. It is stored as update_check_hours (sanitized to those choices), the background loop reads it each cycle, and changing it restarts the schedule at once. The choice is disabled where automatic checks don't run (checks off, debug builds, Snap).

Release notes. When an update is offered, the Settings footer shows What's new in Carrier X with that release's own notes from the signed update, as plain text. The native command returns notes only while it still offers that exact version.

Safer refresh. When Settings regains focus, a new UpdateConsentController.refresh() re-reads the retained discovery: it shows a newer offer, or returns to "Check for updates" when the offer was cleared, so a cleared offer can never be installed by the next click. It never interrupts a check or install, including one that starts while it reads. Tests cover both.

Part of [#262]; the preview channel and rollback are still to come.
