feat(github): add anti-spam protection for GitHub Issues (#14333)
- Add config.yml to disable blank issues and guide users to proper channels
- Add anti-spam.yml GitHub Actions workflow with:
- Keyword-based spam detection (airline names, multi-language terms)
- New account detection (< 7 days)
- Auto-close, label, and lock spam issues
- Remove deprecated old-issue-template.md
This addresses the recent spam bot attacks targeting the repository.
