Add verified_sender catalog entry (30 locales) + live seal repaint on verify

The accessibility label existed only in code, so VoiceOver read english
in 29 locales; the coverage test can't see source-only keys. Also forward
peerIdentityStore.$verifiedFingerprints into objectWillChange so toggling
verification repaints rows in an open DM instead of waiting for the next
unrelated invalidation.
