feat(settings): add option to suppress config reload toast (#2730) (#2915)

* feat(settings): add option to suppress config reload toast (#2730)

Add a toggle in Settings → Compositor Layout to disable the 'config reloaded' toast for Niri and MangoWC compositors. Session setting showConfigReloadToast defaults to true.

* chore: update settings search index for config reload toast

* refactor(settings): rename 'Compositor Notifications' to 'Compositor Toasts'

* fix(settings): reuse existing I18n.tr('Notifications') translation
