fix(companion): reply to the right author in rooms (and keep nicks UTF-8)

Browse Source 
A room is viewed through DM history, where each post is stored "Author:
text" and shown attributed to that author. The reply path, though, built
the @[nick] prefix from _sel_contact.name — the room server's own name —
so replying to someone's post in a room addressed the room, not the person.

New buildDmReplyPrefix() derives the addressee from the same author the
history shows (via dmDisplayParts): the post's author in a room, the
contact name in a 1:1 DM. It also stores the nick raw (UTF-8), like the
channel reply path, instead of running it through the lossy display
transliterator — the prefix is sent over the air verbatim, so a non-ASCII
nick was previously corrupted on the wire.
