fix(gitea,projman): type safety for create_label_smart, curl-based debug-report

Fixes multiple issues from diagnostic #123:

1. create_label_smart type safety (labels.py)
   - Add isinstance(result, dict) checks after API calls
   - Return structured error dict if API returns unexpected type
   - Prevents "list indices must be integers" crash

2. debug-report always uses curl with labels
   - Remove MCP option - always use curl for marketplace issues
   - Add label ID fetching step (Source/Diagnostic, Type/Bug)
   - Include labels in curl POST payload
   - Avoids branch protection restrictions on main branch

Fixes #123
