The handover stops this app's polling loop when the screen goes away,
because the background service takes over. That is right for messages
and wrong for a call already in progress: the loop is the only thing
that routes `call-end` into the manager owning the call screen. The
service polls too, but it turns offers into notifications and knows
nothing about a call that is already up.
So a call ended by the far end while this app was off screen had nowhere
to land. The screen stayed, still offering to answer, until the dial
guard gave up forty-five seconds later. Seen on a device: a call placed
at 13:04:13, no `call-end` ever logged, ICE closed at 13:04:58.
Polling now refuses to pause while a call is dialling, ringing,
connecting or active.
And a backstop for when the signal is genuinely lost. ICE DISCONNECTED
was a no-op, so nothing noticed a far end that simply vanished. It now
arms an eight second grace, cancelled if the connection recovers,
because WebRTC blips are ordinary. A call whose audio has stopped is
over whatever the signalling says.

The notification's Accept button has carried EXTRA_ANSWER_CALL since it
was written, and nothing ever read it. Pressing Accept did what any
other tap did: it opened the app. Answering was left to the next turn of
the polling loop, which refuses a parked offer older than the caller's
patience, so a call taken a little late opened the app onto nothing and
looked like it had dropped the moment you answered it.
MainActivity reads the extra now, on a cold start and on a warm one,
and answers at once rather than waiting for a tick.
The notification also goes away on its own when the offer it shows has
expired. Before, it could outlive the offer by the gap between service
sweeps, which is longer since the loop started holding its poll open,
and during that gap it was a button that could only disappoint.
Seen on the emulator: Accept pressed, app opened, nothing on screen.
