Fix: Resolve relative path issue in backup script git operations

- Convert backup file path to absolute path before git add/commit
- Fixes 'pathspec did not match any files' error when using ../
- Use absolute_backup_path consistently in commit_to_git()
- Tested successfully: backups now commit to git without errors
