fix(calls): incoming-call ringtone respects quiet hours, DND, Focus Assist and snooze

The "should we make noise" predicate used for message sounds is extracted
into useNotificationsQuiet() (unit-tested) and applied to the ringtone in
both the full-screen incoming-call overlay and the compact in-call banner.
The overlay/banner still show so the call can be answered; only the audio
is skipped. Join/media paths untouched.

Fixes #28
