- Message action pill gains a Forward button; tapping it enters selection mode
(tap bubbles to multi-select, footer bar shows count + Forward/Cancel, Esc exits).
- Forward picker lists EXISTING conversations only (DMs + groups from the sidebar),
searchable, multi-target. POST /api/messages/forward copies body+attachment into
each target (authorized as participant/member), live-pushed like a normal send.
- /files auth now accepts ANY message carrying an attachment (allByAttachment), so
forwarded images stay viewable for the new recipients.
