feat(call): Details card for the call-ended toast (#253)

The call-ended toast gets a Details button (and stays 10 s) that opens a
card with who was in the call and the peak, connection verdict and
reconnects, how long your / each person's / everyone's connection was
poor (likely the server when everyone), RTT, packet loss and jitter, and
your talk, mute, deafen and screenshare time, in technical wording.
Deafened time is tracked by CallEmbed; the rest comes from the fork's new
io.lotus.call_summary `details` (lotus.29). Settings → Calls gets
"Summary After Calls" (on by default).

Fixes #253
