Reduce JS libs dependencies via HTMX 2

[phillxnet]

HTMX looks to be the right way to go on this front, especially given:

See/hear: https://talkpython.fm/episodes/show/437/htmx-for-django-developers-and-all-of-us

There is also Django middleware and PyCharm plugins.
PyPi: https://pypi.org/project/django-htmx/
Project Changelog: https://django-htmx.readthedocs.io/en/latest/changelog.html

The aim here would be to swap out the entirety of our rockstor-jslibs for whatever is required to do the same but via HTMX. And in the process eradicate our hands-on JS need entirely; hopefully.

This would be a piecemeal approach where we do one page/section at a time type as we gain familiarity, so likely an initial enlargement of our dependencies: but ultimately the proposed aim here is to standardise on HTMX entirely.

As of this comment, we have a release announcement for htmx 2.0.0, initially known as the next variant as latest is to remain reference for compatibility purposes to the original 1 series untill Jan 1, 2025.

We should skate to where the puck will be on this front: given we are starting out fresh with htmx in our pending testing phase (hopefully).
