Turbo search index

[DanielJackson-Oslo]

Refactor from JS based search to Turbo based search. This is meant to be a base line for future work on the search features, to make that work easier.

Todo:

• [x] Stop using JSON for search results
• [x] Working filter for title
• [x] Working filter for facilities
• [x] Working filter for place
• [x] Working filter for space type
• [x] Run search whenever filters change
• [x] New function for showing spaces on map
• [x] Remove filtering from mapbox controller?
• [x] Update URL
• [x] Get filter capsules back
• [x] Make it more performant and snappy
  • [x] Make sure map is not reloaded, only search content, capsules and markers
  • [x] Look at SQL queries and make sure we only do 1 per search
  • [x] Add loading state while loading a new search
• [x] Store searches for user: Store a given search string in user session, and restore it upon revisiting the search
• [x] Check if personal space lists are affected by all this, especially by filtered_facilities
• [x] All tests pass

This is a tradeoff in UX, but will pave the way for improvements to come.
