fix: prevent resizing of original file with withoutEnlargement on update (#12291)

This PR updates `generateFileData` to skip applying `resizeOptions`
after updating an image if `resizeOptions.withoutEnlargement` is `true`
and the original image size is smaller than the dimensions defined in
`resizeOptions`.

This prevents unintended re-resizing of already resized images when
updating or modifying metadata without uploading a new file.

This change ensures that:

- Resizing is skipped if withoutEnlargement: true

- Resizing still occurs if withoutEnlargement: false or unset

This resolves an issue where images were being resized again
unnecessarily when updating an upload.

Fixes #12280
