[configuration][dicom_archive] link error on config regex when trying to access dicom_archive

[regisoc]

Describe the bug

When any of these 4 regex configuration is empty (at least one):

• Patient ID regex (patientIDRegex)
• Patient name regex (patientNameRegex)
• Lego phantom regex (LegoPhantomRegex)
• Living phantom regex (LivingPhantomRegex)

A permission error is raised trying to access the dicom_archive module.
Links can be found at least in imaging_qc table and imaging_uploader table.
The error message shown is not indicative of what is happening.

To Reproduce

Steps to reproduce the behavior (attach screenshots if applicable):

1. Go to menu > admin > configuration
2. Click on 'imaging modules' and empty one of the regex fields:

3. Go to menu > imaging > imaging quality control (could be imaging uploader too)
4. filter the table by Tarchive = In DICOM Archives
5. Click on one of the link In DICOM found in the table column Tarchive
6. See error
7. When putting at least the most basic regex inside these configurations (i.e. .), the link in the imaging qc table works.

What did you expect to happen?

A clear error message to target these configurations.

This is expected when a config is missing.
