The Forward dialog forwarded blind. Add three things (design-system
cleanup included):
- Preview: a compact read-only preview at the top of the dialog shows the
sender + body, with a thumbnail for image/video (reuses ThumbnailContent
and the getMemberName/getMemberAvatarMxc/trimReplyFromBody helpers). We
already hold mEvent, so nothing is fetched.
- Comment: an optional "Add a comment" field sends a short m.text note to
each target room, sequenced BEFORE the forwarded message per room so the
note reads above the quoted content. The existing per-room failure /
retry logic is preserved (a room fails if either send rejects).
- Recent targets: a "Recent" chip row (hidden while searching) offers
one-tap selection of rooms you last forwarded to. Successful targets are
recorded most-recent-first, deduped, capped at 8, in localStorage via the
pure, unit-tested addRecentForwardTarget (state/recentForwardTargets.ts).
Rooms you've since left are filtered out of the row.
Also replaces the hardcoded rgba(0,0,0,0.35) sending scrim with a
token-free opacity dim of the list (design-system rule: no hardcoded
colors).
