Subject: [PATCH] feat(footer): Add fallback footer and improve file reading

- Use resources.Get for safer file reading instead of readFile
  - Prevents directory traversal attacks
  - Ensures file access within Hugo's assets pipeline
  - Better error handling for missing files
- Add fallback copyright notice when footer.md is not found
- Add warning message for fallback to default footer
