When the app restarts and reconnects to relays, old call offer events
from completed calls could be replayed, causing the phone to ring for
calls that already ended. This was especially noticeable when the user
killed and restarted the app shortly after a call.
Three protections added to CallManager:
1. Track completed call IDs: hangup/reject events mark their call-id as
completed. Subsequent offer events for the same call-id are ignored.
2. Init timestamp guard: events created before the CallManager was
initialized (minus a grace period) are rejected, preventing stale
events from a previous app session from triggering ringing.
3. Completed call IDs survive reset(): the set is intentionally not
cleared when the call state machine resets to Idle, ensuring that
stale offers remain blocked for the lifetime of the CallManager.
