fix(concord): store the kind-13302 list replaceably so the hub populates

The Concord hub was empty even after the 13302 arrived: ConcordCommunityListEvent
extended plain Event, so LocalCache filed it by id and the dispatch when() had no
branch for it — it fell through to consumeRegularEvent. But ConcordChannelListState
observes the addressable note at Address(13302, pubkey, ""), which never received
the event, so liveCommunities stayed empty.

Make ConcordCommunityListEvent a BaseReplaceableEvent (kind 13302 is a NIP-01
replaceable — fixed empty d-tag, address = (kind, pubkey, "")) and add the
consumeBaseReplaceable branch next to the kind-10009 list, so it lands in the
addressable cache exactly like its NIP-29 sibling. The plane-wrap path (1059 ->
concordSessions.ingest in DecryptAndIndexProcessor) was already correct.
