- Introduced the `clean_extra_args` function to filter out unsafe CLI flags and comment garbage from `ExtraArgs`, improving backend configuration integrity.
- Updated the `repair_extra_args_on_disk` function to rewrite corrupted `ExtraArgs` lines in the FDS file, ensuring cleaner backend settings.
- Enhanced the `recover_errored_backends` function to utilize the new sanitization logic, preserving valid `ExtraArgs` during backend reconfiguration.
- Improved the `sanitize_backends_fds` function to drop comment garbage and retain valid entries, enhancing overall backend management.
- Added tests to validate the new sanitization behavior, ensuring robustness in handling `ExtraArgs` during backend operations.
