feat: Add NTP clock sync to Clock settings

Adds a "Sync Clock" action in Settings > Clock that connects to WiFi
(auto-connecting to saved networks or prompting for selection) and
performs a blocking NTP time sync. Shows the synced time on success
with an auto-dismiss countdown, or an error on failure.
