fix: Prevent false offline notifications for normal sync states

The sync service's Idle and Running states are normal operational states
that should not trigger offline error popups. Only Error, Terminated,
and Offline states indicate actual connection problems.

This fixes the issue where users would see 'Cannot reach Matrix homeserver'
error incorrectly after registration when the sync service is actually working.
