MBS-14013: replace date editor with a react component

[dvirtz]

Problem

MBS-14013: entity create fails silently when begin date > end date

Solution

replace artist date editor with a react component

[dvirtz]

Tests fail because HydratedDateRangeFieldset is missing begin/end area
edit: it also doesn't support different labels per artist type

@reosarevok did you have a chance to review this?

[dvirtz]

BTW, @reosarevok I did this before you asked me to consult you before implementing features in #3565 (comment) (although this is not a style issue so maybe that's not needed).
Feel free to reject it if you prefer a different solution.

[reosarevok]

No, this is not style so that doesn't matter :) I haven't had time to check this (just came back from a holiday) but I will try to find some time. Did you manage to make it "support different labels per artist type" now? :)

[dvirtz]

No rush, I just wanted to know if you plan to review it or not.
It should change the label based on type now.

[reosarevok]

Tested this locally and it does work, but @mwiencek might have comments about the code itself, so I'd want his review here.

Thanks for working on this! There's one bug which needs to be resolved, and it might take a bit of effort.
