Hello Gergő,

thank you for this suggestion, however it still does not work on UploadWizards special page. :(

Just to cross-check if MediaWiki recognizes my translations I added {{int:mwe-upwiz-license-c}} to my test page. Here everything shows up as expected.

Anyhow I just created a task on Phabricator for this [0].

Thanks for your help!

You need to also add it to the message dependencies of the ext.uploadWizard ResourceLoader module - backend logic can look up messages on the spot, frontend logic cannot.
Probably something like
$wgExtensionFunctions[] = function () {
    $wgResourceModules['ext.uploadWizard']['messages'][] = 'mwe-upwiz-license-c';
would work. Although UploadWizard should do this itself if it exposes its messages to be configurable, so I'd say this is a bug.
