The DM "Message button" test asserted addDmChannel was called with two
arguments — the channel and an empty-string origin — but the assertion
has been stale since commit 7f3ca4e ("route DM creation to home instance
with federated identity", 2026-04-01). That refactor made FriendsPage
always route DM creation through the home api client and dropped the
second argument from the addDmChannel call because the remote friend's
instanceOrigin no longer applies — home-created DMs don't need a
channelOriginMap entry (lookups default to '' for missing keys; remote-
delivered DMs still get their origin tagged by useWebSocket).
The two-arg assertion was introduced on 2026-03-25 (commit 277b69a)
against an intermediate form of the code that was later rewritten. Drop
the trailing '' so the assertion matches the current, intentional
one-arg call.
