[Bug]: Files larger than 128 GiB cannot be unpacked into an ext4 image

### I have done the following

- [x] I have searched the existing issues
- [x] If possible, I've reproduced the issue using the 'main' branch of this project

### Steps to reproduce

1. Create an image with a single file above 128 GiB.
2. Run:
```
bin/container image load --input large-image.tar
```

### Current behavior

```
Error: 137439084544 exceeds max file size (128 GiB)
```

### Expected behavior

No error, but only if unpacking wouldn't run out of disk space.

### Environment

```markdown
OS: macOS
```

### Code of Conduct

- [x] I agree to follow this project's Code of Conduct

Start by reproducing the issue with `bin/container image load --input large-image.tar`, then trace the image-unpacking path for the 128 GiB file-size limit and ext4 image handling. Done means a file larger than 128 GiB can be unpacked when disk space allows, while insufficient disk space still produces an error.
