fix(discord): the connector's STOP refusal names the journal by label (#1873)

Re-check 3 found connector.start() still quoted the journal directory in
its STOP refusal, and the CLI passes a DiscordError through unchanged.
It now uses journalLabel like the CLI and journal refusals. The connector
test asserts the path is absent: 22/1 on the old source, 23/0 after.
