feat(nests): add visible kebab menu to room cards

Long-press on the cards already opened the standard
NoteQuickActionMenu, but the affordance was hidden — especially on
the compact ENDED card which has no visible interactive elements.

Add an explicit MoreVert (VerticalDotsIcon) tap target that opens
the same menu:

- ENDED compact card: 40dp icon on the trailing edge of the row.
- LIVE/SCHEDULED full card: 35dp icon in the existing
  SpaceHostAndReactions row, after Like and Zap.

Both wire through the showQuickAction lambda from
LongPressToQuickAction, so the icon and the long-press gesture
trigger the exact same menu (share, copy, broadcast, report,
block, delete) — no second popup-state plumbing.

ObserveAndRenderSpace, RenderLiveSpacesThumb, and
SpaceHostAndReactions gain an optional `onMore: (() -> Unit)?`
parameter so other callers (e.g. existing live-stream surfaces
that reuse SpaceHostAndReactions) keep their current rendering
unchanged when they don't pass one.
