[Editor]: Warn user if draft has been updated

[cmoinier]

Description

This PR introduces a warning when the user starts editing one of their drafts, if the record has been updated by another user since they created the draft.
Key features :

• Added detection for record change in backend when a draft is opened
• Added the update of recordUpdated field when the draft is created, to be able to compare the draft's date with the record's date in the backend.
• Added a banner at the top of the edit page when the record has been updated by someone else
• Added an overlay warning message when the user tries to publish their version on top of someone else's, with cancel/proceed choices
• E2E tests : to mock 2 users editing the same record in e2e tests, it's been decided to clear and re-populate the localStorage between 2 editions by the same user

Thanks, @cmoinier ! Congrats for the clean PR on this essential feature ! I left a couple of comments with ideas in-line.

Almost everything works really well. I just discovered two egde/minor issues:

• When editing the same record (that has not been saved as a draft yet) at the same and submitting it on both sides, the one submitting last can still overwrite the changes of the one submitting first without being warned.
  => This might actually be out of scope for this ticket/PR, not sure.
• The popup does not close when accepting to overwrite changes.

Also, we should remember to clarify why we get a 400 error for non-admin users when submitting changes.

Thanks for the adaptions @cmoinier !

The issues mentioned above are fixed. There is a small glitch when aborting changes after the warning and reverting them, they are not applied in the open form. This may be out of scope for this PR.

There is still an issue with the date formatting in the tests, potentially because the CI runs in a different timezone. I think you could rely on the angular pipe for formatting here and get rid of the test. I let you fix this and approve.

Just had a look at the e2e error log and I think the following errors are actually related to this PR, the issue on reverting changes I mentioned earlier:
