fix(ci): set cancel-in-progress=true on merge-queue workflow

`cancel-in-progress: false` causes the Gitea Actions scheduler to freeze
when a cron tick fires while a previous run is still executing. Pending
entries accumulate indefinitely and no new runs dispatch. This was the
root cause of the queue freeze during SEV-1 2026-05-17.
