Replace MUI DatePicker with react-datepicker

[snoesberger]

This PR fixes #948 #920 #614 and, as mentioned in #614 (comment), the react-datepicker brings also some advantages over the MUI DatePicker.

With this PR, there is still the statistics component that uses the MUI DatePicker. I haven't been able to replace it because the stats feature doesn't work properly in the new admin UI, see #282. Once this is working again, the MUI DatePicker can also be replaced there and the dependencies can be cleaned up.

It may take a few seconds for the interface to spin up.
It will then be available at http://127.0.0.1:3000.

I looked into the above mentioned link. Selecting dates in the Startdate-filter, event-schedule and event-metadata works fine. Would it be possible to focus the datepicker when it is opened - having the focus allows navigation with i.e. cursor-keys and pgup/pgdown. Getting the focus manually needs some learning as the picker closes on single-click, tab closes the picker.

Nice. :) Focus works for me.

The date range picker for the start date filter no longer has a year (I'm sorry I didn't see it yesterday).
It's fine by me, I can just press and hold pgup or pgdown for a short while (or shift+pgup/down for year) to get to the year I want. But maybe there is an easy way to add a UI-selector for year or year-month?

In the event schedule start date: When I try to change the year (yyyy) by typing it in, the year is evaluated after the 2nd digit, I would have expected, that it lets me type all 4 digits - this is not related to the react-datepicker I think?

Yes, I thought about this too, and there is even a way to add a drop down with month/year to choose from (showMonthYearDropdown prop). But the thing is, if you want to use this drop down, you also have to define a minDate and a maxDate. This will limit the dates you can choose from. (see also the following issue: Hacker0x01/react-datepicker#2553)
Because it's not easy to choose a min and max date that suits everyone, I didn't activate the drop-down. And as you mentioned, you can still quickly change the year with shift + pg up/down.

This problem doesn't seem to be related to the react-datepicker, at least I have similar problems with the old datepicker. Maybe it has to do with conflict checking? We should probably cover this in another issue.

I had another look at it and found another way to achieve the ability to easily change the month and year. I added the functionality in the last commit.

I had a look into the the date range selection of the start date filter.
It now has dropdowns for month and year, which work as intended by you. 😀

I'm not able to focus the dropdowns via tab-cycle, but I don't see it as a big issue since the (shift+) pgup/down-keys are there.
