fix(sre): gitea-merge-queue list uses label not labels API param

Gitea 1.22.6 /issues endpoint: the plural `labels=` query param returns 0 results even when PRs carry matching labels. Singular `label=` works correctly. This bug made the queue appear perpetually empty (mc#1099 follow-up: queue cron never picked up PRs). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
