Persisted notifications were restored with their saved 'dismissed' state, so any
that were still active when the page closed came back as active toasts — but
their auto-dismiss timers aren't re-armed on load, leaving them stuck on screen
forever (a burst of errors could pile up dozens). Mark restored entries as
dismissed on load: they stay in the bell history but no longer reappear as live
toasts. The toast surface is session-transient; history persists.
