Kyle Pope 360a14b87b Restore refetchIntervalInBackground for unread count polling
The W-03 QA fix (removing refetchIntervalInBackground) broke toast
notifications when the receiver tab is hidden (e.g. user switches to
sender's tab). Without background polling, unread count never updates,
NotificationToaster never detects new notifications, and no toast fires.

Restored with explanatory comment documenting the dependency.
