fix: check Gitea API response status and fallback for PR reviews (#47)

## Summary
- Add HTTP response status checking to all Gitea tracker methods that were silently swallowing errors
- Add fallback in create_pr_review: if inline comments fail, retry as plain PR comment

## Test plan
- [ ] Deploy and trigger a PR review, check logs for actual error details
- [ ] Verify fallback posts summary comment when inline comments fail
