Soulseek album poll: treat 'Aborted'/'Cancelled' transfers as failed

Live testing surfaced that slskd reports a peer-side abort as 'Completed,
Aborted' at 0 bytes (peer accepts then drops every transfer). That string
contains 'Completed', so the poll's completed-branch ran first and misread it as
'completed but file missing' — routing it into the #715 unresolved/download_path
grace (gives up after 45s with a misleading 'download_path mismatch' log)
instead of recognizing it as a failure.

Add 'Aborted' and 'Cancelled' to the failure-token check (which runs before the
completed branch), so these resolve immediately and correctly as failed. Test
added for the all-aborted folder.
