Translate files / attachments

I'm working on this, current status can be found in the merge request, mime type based extraction of files in file fields, handling to translation provider and saving again is working, started working on the review UI.

UI is working pretty well now, files are shown on the review page, and the job checkout and overview view has file count fields. On the view, it will need to be added manually, I don't plan to do that automatically.

Settings were moved to the main module and there's a annotation property now so that translators can flag themself as supporting files and only then the UI elements and settings will show up.

This has been tested manually and we have automated test coverage as well.

A first real implementation for this was developed in for tmgmt_xtm in ✨ Support file translations Needs work . Other translation service providers who wish to support this new feature can look at the implementations in the TestTranslator as well as that module or get in touch with us.
