feat(web): Global map showing all assets with geo information (#2355)

* First crude implementation of the global asset map in web

* Use single DOM element for all markers

* Minor layout changes

* Refactor

* Add asset viewer

* Add API endpoint that returns only assets with location information (Thanks @EPP100)

* Remove sidebar icon flip

* Add dark theme support

* Center map to most recent asset

* Allow cluster viewing

* Fix linter errors

* Add newlines

* Fix ts errors

* Fix eslint error

* Run prettier

* Server code style

* Fix openapi mobile code generation issues

* Map markers test

* fix: Support video thumbnails

* Update API

* Review suggestions

* Review suggestions

* Linter error

* Chage mapMarker endpoint to map-marker

* Clean up leaflet imports
