[marius-at-atb]

DRAFT

This is a branch with (almost) everything put together.
Planning to merge as a series of PRs:

- Design System - Add Icons // replaced by sprite solution

• Create sprites and make them available at some url

• Remote config

  • Url for tile server endpoint
  • Mapbox style source for stop places

• Update to new map style

  • New map style env vars
  • Use new style URL based on light/dark mode
  • StopPlaces -> added using VectorSource, supporting selection of active stop place

• Optional: Use new style for all maps in app

  • Update map config to use the new map style
  • Add StopPlaces to relevant maps, e.g. live bus in map.

• Vehicles and Stations

  • Remove all legacy code, use VectorSource, supporting selection of active stop place
  • Fix for map filter
  • Handle onClick logic (not done in this Draft PR)

• Deprecate old BFF endpoints

• Documentation

Uses and depends on the server tile endpoint: https://github.com/AtB-AS/mobility/pull/35.

Resolves https://github.com/AtB-AS/kundevendt/issues/19555

Also just for entertainment, here's a screenshot from the development of the new map solution:

Hmm, max limit means we should get this through our own server (or contact mapbox).
