Audit-driven UI fixes that don't fit the perf bucket:
* NestActionBar — wire StopBroadcastButton between MicMuteToggle and
LeaveStageButton while broadcasting. The doc table at the top of
the file already advertised [Mute] [Stop] [Leave the Stage] but the
button was defined and never used; speakers had to leave the stage
to stop sending audio.
* NestActivityContent — render an explicit loading spinner while the
kind-30312 resolves and a clear "this room can't be opened" page
with a Back button when the event is missing service/endpoint.
Replaces the previous black-screen dead end.
* HandRaiseQueueSection — wrap filter+sort in remember so a heartbeat
doesn't rebuild the queue on every recompose, swap to LazyColumn
so a long queue doesn't render every row every frame, and show
UsernameDisplay instead of the raw 8-char hex prefix.
* CreateNestSheet schedule picker — compute the timezone offset at
the picked instant rather than at Instant.now(); the previous
variant was off by one hour for rooms scheduled across a DST
transition.
* NestViewModelFactory — pass OkHttpNestsClient's httpClient via
named parameter so the (String) -> OkHttpClient function reference
doesn't get bound to the Long callTimeoutMs slot. Fixes the
pre-existing :amethyst:compilePlayDebugKotlin failure on the
branch base.
Adds three strings (loading, unjoinable title/body, back).
