feat: Implement AppLifecycleService and refactor to fix auto updater

[charlesvien]

Alright here's what I found in the cave...

the bug: when autoUpdater.quitAndInstall() was invoked, it triggered the before-quit event, but the handler would intercept it, prevent the default behavior, and forcibly exit the app before the updater could complete its installation flow.

solution: this PR introduces a new AppLifecycleService that centralizes all shutdown logic and tracks an isQuittingForUpdate flag. Now when installing an update, the UpdatesService first calls lifecycleService.shutdown() to gracefully clean up, then sets lifecycleService.setQuittingForUpdate() before calling quitAndInstall(). The before-quit handler now checks this flag and returns early if set, allowing the auto updater to proceed unblocked. This separates the "normal quit with cleanup" path from the "quit for update" path

NOTE: There is a different event sequence for quitAndInstall()

Excerpt taken from electron docs

The Event Sequence for quitAndInstall()

Normal quit:

1. before-quit emitted
2. Windows receive close events
3. Windows close
4. will-quit emitted
5. App exits

quitAndInstall() sequence (different!):

1. All windows receive close events first
2. Windows close
3. before-quit emitted after windows are closed
4. Installer runs
