Feature request: "shortcut" menu item for new item creation against a chosen reconciliation service

[trnstlntk]

Idea from @lozanaross, endorsed by me, which we discussed in the context of Wikimedia Commons user testing sessions.

Creating new items via reconciliation services is a confusing process, as we regularly see in demos or user tests. People first have to reconcile non-existent entities (eg not yet existing Wikidata items or Wikimedia Commons filenames) against a reconciliation service, and then mark them as new. We propose a shortcut to make this process easier and probably more logical.

Proposed solution

Add a menu item which may be something like Create new items via reconciliation service...
When selecting this menu item, the user then gets a small dialog, very similar to the one produced by the Use values as identifiers menu command, saying: Create a new item for each of the selected cells, against reconciliation service: with a drop-down menu that allows the user to choose between all the reconciliation services they have installed.

(The idea is that prior reconciliation before this process then would not be necessary.)

Alternatives considered

Keep the current situation with very confused users.

Absolutely! I proposed exactly that some years ago already :)

To add to the specification: the new dialog should only be shown for columns that are not reconciled already.

Let's close #1608 and keep this one open.
Also removing the wiki commons label because it is independent of Commons (the fact that it is relevant to the Commons integration project is represented by the project assignment)

Two wireframe mockups are relevant to add here:

1. How to select the action to directly create new items (or media uploads) (without going through reconciliation process first, which is a pain point even when using Wikidata/Wikibase). To do this a slight reorganization in the order of action menu items is proposed, see below (the items are re-ordered because items below the line require reconciliation first - perhaps a contradiction that needs resolving as well):
   

2. What happens when that action from the menu is selected, a customized dialog window is opened:
