refactor(desktop): drop keep-awake statusbar toggle; persist in main

Keep-awake lives only in Settings → Advanced now. Remove the statusbar
quick-toggle (+ its Sun icon, store toggle helper, and keepAwakeOn/Off
strings across locales). Since the statusbar was what eagerly loaded the
store at boot, move persistence to the main process (keep-awake.json,
re-applied on app ready — same pattern as translucency), so a cold launch
restores the blocker without the renderer opening Settings.
