Heimdall's Discord callback issues a random completion code distinct from
the attempt id, but the vendored adapter required the two to be equal and
rejected every real return as a malformed witness, so no player could sign
in. Re-vendored from Heimdall e8e2832, which completes by attempt id and
never reads the completion code; the test fixture issues a distinct code as
the server does.
A player who finishes Discord elsewhere and switches back to this tab never
reloads it, so the load-time resume never ran. The page now reruns the same
resume when it becomes visible with an attempt in flight.
