refactor(crew-chat): Chat tab is always NIP-17; widen group read window
Per the crew-chat audit recommendations: - The crew Chat tab no longer silently switches transport on a coordinator tag. It is always NIP-17; coordinator routing lives only in the Private chat (MLS). useCordnChat / useCrewChatUnread / lib/cordn client+crypto are kept but unwired (headers marked). Drops the tab's Cordn-only unread dot. - Group reads (Groups list + crew thread) widened 200 -> 500 wraps; the shared decrypt cache makes the extra reads affordable. 1:1 list stays 200.
