Expose in-app update checks and installed version

[Wirenut33]

Expose Check for Updates in QuickShot's application menu and Settings, in addition to the camera menu. Settings displays the installed version and explains automatic background updates. Sparkle's live state disables the action while a check is already running.

Validation: signed universal Apple Silicon/Intel build passed. The existing main release pipeline has now completed successfully, including encrypted-secret import, app/feed signing and GitHub Release publication.
