fix: add label ID resolution to Gitea create_issue

Problem:
- Gitea API expects label IDs (integers), not label names (strings)
- Previous implementation passed label names directly, causing 422 errors

Solution:
- Added _resolve_label_ids() method to convert names to IDs
- Fetches all labels (org + repo) and builds name->ID mapping
- Automatically resolves IDs before creating issues

Testing:
- Created test issue #4 with 4 labels (manual verification)
- Created test issue #5 with 11 labels (automated testing)
- All labels applied correctly in Gitea

Also updated:
- projman/skills/label-taxonomy/labels-reference.md with current taxonomy
- Status updated to "Synced with Gitea" (43 labels total)
