Remove uses of `get_file.php` for non-old-DQT modules

[MaximeBICMTL]

As discussed in the meetings, the get_file.php endpoint is unsecure to use outside of the old DQT. Unfortunately, it is currently used by some other modules, so the uses of this endpoint in those modules need to be removed.

I did not manage to make an URL out of a GitHub code search (if someone knows how to please show me!) but I could find the following uses that beed to be removed (see screen below):

• Electrophysiology browser
• DICOM archive
• Imaging browser

Solution:

• Use the API instead (hopefully all endpoints are available).

I was not here when it was originally discussed in the meeting, but I am assigning Adam as it seems to be what was decided in the agenda. I am not sure this is the right call though... Maybe a security issue should be handled by someone more familiar with these modules or the API. I am also adding a "Critical to release" priority because I think this is too big of an issue to ignore.

@MaximeBICMTL is this something you want to take on?

Sorry @adamdaudrich but nope, I found and reported the issue but I have other things to do unfortunately.
