feat(threadview): render Nest cards in NoteMaster

When the thread-screen master note is a kind:30312 MeetingSpaceEvent
(Nest) or kind:30313 MeetingRoomEvent, route through
RenderMeetingSpaceEvent / RenderMeetingRoomEvent — same path
NoteCompose uses for non-master entries (NoteCompose.kt:1034-1040).

Without this, the master note in the ThreadFeedView's FullBleedNoteCompose
fell through to the generic note body and showed neither the Nest card
nor the Join CTA. Users who landed on a Nest via search, quote, or naddr
deep-link saw a blank-looking thread; tapping the in-feed card now (since
the routing fix in 98202b6) opens NestActivity directly, but the thread
view itself was the remaining gap.
