Contents of the save dialog (summary and checkboxes) should be stored together with the document.
Scope of this task:
- They are preserved when restoring autosaved edits
- They are preserved when switching OWE↔VE, NWE↔VE, and when switching to edit conflict resolution
- Code in ve.init.mw.DesktopArticleTarget handling initialEditSummary and initialCheckboxes is removed and this is re-implemented in init
- All of the above also works on mobile
(This task is a follow-up to T250388, where I fixed preserving the checkboxes when switching OWE→VE and found that many other things don't work)
