Adds a "Pinned" toggle chip that narrows results to messages currently in
their room's m.room.pinned_events. Client-side post-filter mirroring the
has:image/file/video pattern: a pure filterGroupsByPinned(groups, enabled,
isPinned) helper consumes a predicate; MessageSearch builds a per-room
Map<roomId, Set<eventId>> from StateEvent.RoomPinnedEvents.
Review fix: the msgtype + pinned filters are now applied to BOTH the server
results AND the encrypted/local-cache results (via a shared applyResultFilters
useCallback), so the chips narrow the whole UI consistently — previously the
local/E2EE section bypassed them.
