Self host map tiles

Let's stop using open streep map servers and build an image with tiles (not with all zoom level of course...) fo rus.

https://github.com/openmaptiles/openmaptiles

Also switch to vector tiles and https://github.com/alex3165/react-mapbox-gl

Move from leaflet to mapbox in the front
Update Nginx to serve the tiles directly
Make sure the tiles are only accessible to users from the website
Build an image for the whole world and post it to docker-hub

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
