[Feature] Modern UI roll out (#236)

This PR moves all the collection pages into the new UI in a rough push.
I did not put the same amount of care into these as into search, index, and predict.

## Major changes

- All modals are now migrated to a state based alpine.js implementation.
- jQuery is no longer present in the base layout; ajax is replace by native fetch api
- most of the pps.js is now obsolte (as I understand it; the code is not referenced any more @jebus  please double check)
- in-memory pagination for large result lists (set to 50; we can make that configurable later; performance degrades at around 1k) stukk a bit rough tracked in #235

## Minor things

- Sarch and index also use alpine now
- The loading spinner is now CSS animated (not sure if it currently gets correctly called)

## Not done

- Ihave not even cheked the admin pages. Not sure If these need migrations
- The temporary migration pages still use the old template. Not sure what is supposed to happen with those? @jebus

## What I did to test

- opend all pages in browse, and user ; plus all pages reachable from there.
- Interacted and tested the functionality of each modal superfically with exception of the API key modal (no functional test).

This PR is massive sorry for that; just did not want to push half-brokenn state.
@jebus @liambrydon I would be glad if you could click around and try to break it :)

Finally closes #133
