Route iOS notification settings intent into the app

Request push notification permissions with provideAppNotificationSettings
so iOS surfaces an in-app notification settings button on the system
Settings screen. Since passing an options object opts out of the default
alert/badge/sound permissions, set those explicitly to preserve behavior.

Handle the resulting openSettingsForNotification callback in a new
NotificationSettings sub-module in expo-bluesky-swiss-army, which registers
a NotificationDelegate with expo-notifications' NotificationCenterManager
and converts the callback into a bluesky://settings/notifications deep link
that the existing linking config routes to the notification settings screen.
