Revert embed-based DM body back to plain message content

The embed approach kept surfacing new rendering edge cases (Discord's own
.txt attachment preview showing raw markdown, hard character-count
truncation occasionally slicing through a link's syntax). Reverting to the
simpler "From/To/Subject" + "label (url)" plain-content format, which was
reliable. Keeps the two independently useful fixes from the embed work:
the recipient disposable address now shown in a To: line, and duplicate
links (same URL, e.g. logo + text CTA to the same place) collapsed to
plain text after the first occurrence. Also makes body truncation respect
line boundaries generally, not just for markdown links.
