feat(android): attach photos and camera shots

The (+) door stages gallery picks and camera shots as removable
chips against the daemon's own budget (eight a message, 5 MiB
decoded each, refusals surfaced, never silent drops); send reads
the files back as bare base64, the old {"text"} body unchanged
when there are none. Sent rows preview their staged files at once
and a replay fetches by attachment id like any attachment card.
Model options carry the vision badge only when the listing knows.
