[media] Translate Project in media and imaging_browser modules

Extracts the Project translation part of #10548 which did not cause test failures into a different PR.

'Rye' is translated into 'Seigle' in french so the following images show that the translations went through.

imaging_browser:

media:

statistics: there is already a translation for the project label done inside the module but it would simplify code if reverted. and other similar instances can be reverted too because you just included the translation of the name in the utility function itself.

here's a screenshot after I applied (it can be left as is, would still work but better to remove this redundancy)

@HachemJ Reverted the statistics double translation

your last change in the imaging_browser module successfully translates the project labels in the 'Project' column of the table displayed in imaging_browser. LGTM
