Archive Conversation

Take a conversation off this trip's page.

What that MEANS depends on the link, because the roster now lists chats this trip does not own. A chat filed here (primary) is archived, as it always was. A chat that merely REFERENCED this trip loses the reference row instead: archiving is global, so archiving one would silently pull a chat off the user's phone because they tidied a trip page on the laptop. Both arms leave the trip page, which is the whole of the caller's intent.
