PY-613 BUG: Unable to export Nifti files without file extension.

The team at Kaliber are unable to export DICOM files they've annotated as the files don't have filenames.

The customer has shared that they receive error JSONs after exporting that shares this message: "{"error": "You are trying to export to nifti. Filename should contain either .nii, .nii.gz or .dcm extension. Are you sure this is medical data?"}". Because of this, they don't have a way to export their DICOM files as Nifti within the platform.

N/A

Impact:

• Single (only one customer impacted)
• Some (few customers are impacted)
• All (all Darwin users are impacted)
• ⚠️ Strategic customer

1. Upload a DICOM file with no file extension in the filename.
2. Make some annotations on the file.
3. Attempt to generate an export with the file using Nifti format.
4. Once the export is generated, download and open the files.
5. Observe if you receive an error JSON.

Expected Behaviour:

Dataset - https://darwin.v7labs.com/datasets/699814/dataset-management
