Drop moment.js for luxon.js

[yubiuser]

What does this PR aim to accomplish?:

This PR initially only tried to replace https://github.com/dangrossman/daterangepicker which has been unmaintained for >5 years now. I found a active fork at https://github.com/Wernfried/daterangepicker which had the nice side effect that it replaced moment.js (also in maintenance mode) mode with its successor luxon (https://moment.github.io/luxon). I swapped all the libraries and adjusted the code. Not all date/time format could be translated 1:1 but it's close.

It was quite straight forward, but one moment.js function (toHuman()) did not work in luxon.js (with millisecond input it would not translate to human readable output but keep in miliseconds). There is a long-standing luxon bug (https://github.com/moment/luxon/issues/1134) which provided a nice workaround with a wrapper function. I added it, but it required to load luxon.js already in header.lp (opposed to header_authenticated).

I did not implement any of the new features https://github.com/Wernfried/daterangepicker would offer. This could be implemented in a follow-up PR.

While using this PR as a base for implementing the new constrained "All Time" range, I found a bug in the daterangepicker fork, and have submitted a PR upstream to get it fixed
