feat(events): include organizer name in event fuzzy search

Search only indexed title/summary/description/location/tags, so typing an
organizer's name found nothing. Organizer display names aren't stored on
the event (they're resolved per-pubkey into the shared ProfileService
cache), so enrich the search corpus with the resolved name read from that
same reactive cache and add it as a Fuse key. Opening the search overlay
warms the cache for any organizers not yet fetched, and the corpus
recomputes as kind-0 metadata arrives.
