relay: file attachments, outbox, CC-self, chat view, mobile layout
Compose: attach files (encrypted, hex-named, linked via relay_uid),
CC-self checkbox tags copy with recipient name. Outbox section shows
sent messages with delete. Chat view: session-based threads/history/
send endpoints, split layout with sidebar, read receipts, 5s poll.
Mobile: threads as horizontal scroll bar above messages. Fix chat
input pushed offscreen by adding min-height:0 on flex container.
