fix(concord): show the quoted parent on kind-9 chat replies in NoteCompose

A Concord (and MLS/WhiteNoise) chat reply is a kind-9 ChatEvent that carries
its reply target as a NIP-18 `q` (or NIP-10 `e`) tag, not a NIP-10 thread — so
it isn't a BaseThreadedEvent and RenderTextEvent's reply-to preview never fires
for it. On the chat feed the preview is drawn by chat-only code, but everywhere
else NoteCompose routes kind-9 through RenderChat, which rendered only the
content and never `note.replyTo`. Result: on the Notifications tab a Concord
reply showed no quoted parent (no border) — most visibly when replying to an
image, whose target is likewise a kind-9.

RenderChat now takes unPackReply and, when FULL and not makeItShort, renders
ReplyNoteComposition(note.replyTo.lastOrNull()) like the threaded path does,
skipping it when the parent is already cited inline (`nostr:...`) so an
MLS-style quote isn't drawn twice. NoteCompose forwards unPackReply; the thread
view passes NONE since its structure already shows the parent.
