Fix issue-label and pr-rework webhook handlers

- issue-label: Accept action "created" from Gitea (in addition to
  "labeled" and "label_updated") — Gitea sends "created" for new labels
- pr-rework: Guard against missing review object to prevent TypeError
  crash when Gitea sends review webhook without review data
