feat(notifications): add dev/test 10-minute rollover toggle and plugin spec

- Add dev-only "Use 10-minute rollover (testing)" toggle in Reminder
  Notifications (Account view). Visible only when not on prod API server
  (isNotProdServer). Toggle persists and reschedules reminder with
  rolloverIntervalMinutes when changed.
- Extend daily notification flow to pass optional rolloverIntervalMinutes
  to the plugin: NotificationService/NativeNotificationService options,
  PushNotificationPermission dialog options, first-time and edit flows.
- Add settings: reminderFastRolloverForTesting (Settings, AccountSettings,
  PlatformServiceMixin boolean mapping, migration 007).
- Centralize isNotProdServer(apiServer) in constants/app.ts; use in
  AccountViewView (toggle visibility), ImportAccountView, and TestView.
- Add docs/plugin-spec-rollover-interval-minutes.md for the plugin repo
  (configurable rollover interval and persistence after reboot).

Note: Daily notification plugin dependency is currently pointed at the
"rollover-interval" branch for testing this feature.
