Show a video chat plate under the topbar for group calls you haven't joined

The topbar already had a plate for RTMP live streams, but an ordinary group
video chat had no entry point besides the header button. Add a sibling plate
laid out like the other clients: icon and title on one side, the join button
on the other, and a three-face preview of who is already in the call centred
on the plate.

The stack is centred with equal-basis side columns rather than absolute
positioning, so it sits on the real centre (as tdesktop paints it at
`width / 2`) while a long call title can never run under it. On handhelds the
stack shrinks so holding the centre does not clip the participants counter.

Visibility follows every other client: `call_active` + `call_not_empty`, the
call is not an RTMP stream (that one belongs to the live plate), and we have
not joined it ourselves. The joined edge comes from the controller's
`instance` event and the closing edge from the instance's own `state` event,
since the controller keeps its reference after a hang-up.

`getGroupCallPreview` gives the plate the call plus the first N participant
peers in one hop, so the whole participants map never crosses the worker
boundary, and only chats that actually have a call subscribe to the full peer.

Lay the Requests plate out like the translation one

The join-requests plate was the only floating plate still built as a
full-bleed clickable row: faces pinned to the start, title floating in
the middle, close button inside the same ripple area. Give it the shape
every other plate already has — the stretched, centred pill of the
translation plate, with the faces taking the start slot exactly the way
the close button takes the end one, so neither shifts the label off the
plate's centre. The width formula both plates now share moved into
`--pc-centered-button-width`.

Along the way:

- the label never carried `pinned-requests-title`, so its primary colour
and bold weight were dead CSS; it inherits both from the pill now, and
gets `text-overflow-no-wrap` so a large count ellipsizes instead of
wrapping out of the fixed 48px plate;
- the controller reported `height: 52` while the plate has always been
48 CSS px, which made `setFloating` reserve 4px too much;
- avatars go 32 -> 40px, matching the buttons on the plate, and shrink
back on handhelds where the centred label would otherwise run under
them (same trade-off as `.pinned-group-call`);
- the close button is no longer nested inside the clickable area, so
dismissing the plate can't also open the requests tab;
- `<Show>` is keyed and the label is updated from an effect: `set()`
writes a fresh `RequestData` on every `chat_requests` update, and a
plain `Show` kept the previous count and faces on a visible plate.
