fix: use Combobox for notification group selection in settings page

Settings page used a plain number input for ip_change_notification_group_id,
requiring users to manually enter a group ID. Replace it with a searchable
Combobox component (consistent with alert-rule/service/cron pages) and wrap
the settings route with NotificationProvider to load notification group data.

Closes nezhahq/nezha#1174
