refactor(debug): remove unused helper and commented logic in DebugBarOutput

- Removed the `base64_encode_file` helper function from `helpers.php` as it is unused.
- Removed the corresponding test case for `base64_encode_file` in `HelpersTest.php`.
- Commented out the `isEnabled` method call in `DebugBarOutput::isAvailable`, likely for debugging or evaluation purposes.
- These changes simplify the codebase by removing unused functionality and modifying logic handling debug output.
