Save records on creation/duplication and allow attachments

[cmoinier]

First of!

This PR is a joint work of the record creation & duplication tickets, to allow saving the record and adding attachments in both cases.
A huge thanks to @Angi-Kinas @tkohr @ronitjadhav for the joint work on this PR!

Description

This PR makes sure the attachments are available upon record creation & duplication
To this aim, all newly created/duplicated records are now saved but not published. They can be manually published even without any changes done to the new draft.
A new Observable manages that, named savedButNotPublished which carries the information given by the backend for each record, from a search request.
The column "Status" of the dashboard is now also based on the response from the search request, and displays the right info.
It is now impossible in all cases to delete from the draft table (since all drafts have a record).
Multiple UT & e2e have been reworked and/or deleted, since the "draft only" status does not exist anymore.

Architectural changes

• All mentions & uses of alreadySavedOnce are removed because all records are now saved once. An alternative, if needed, if to use savedButNotPublished but no component needs it for now.
• For the same reasons, all mentions & uses of "isDraftOnly" have been removed. In some cases, for safety (because the backend takes a few seconds to save the record), they have been replaced with a check that a uuid exists for the record or not. I'm not even sure that this safety measure is necessary.
• Also did a big update on the italian translations because the CI run was long 😄

Tested, works really well!

I just noticed a slight glitch when creating a record:

the editor form jumps down and back up quickly; the reason is unclear but it was quite noticeable.

Thank you all for your work!

Thanks for catching that :) It was because the "/create" page was loaded for a very short time, because "/edit" was not ready yet. I have added a loading spinner to display the "/edit" page only when it has a record ready, it should be smoother.

Thanks @cmoinier for this huge feature! It was a lot of work and you completed it! 🎉

The code looks good, I just have a few comments and questions. I did not test the feature yet though. Let me know if something is not clear.

Thanks again for your hard work on this!
