Previously we used a radio button that was hard to spot for controlling whether to create new criticals/conflicts and movements/arms. It was very easy to click the map and accidentally create a stray object unintentionally; we saw this several times in the UX studies.

This PR switches to a map panel that makes it more clear what mode the user is in. Note it's still possible to click or drag an existing object even in the "New xyz" mode, but this is harder to fix and maybe even reasonable behavior anyway.

Still would like some advice on improving the map panel styling to make it clear what the current tool is. We could iterate on that later if needed.

I also got rid of the old geolocate and fullscreen controls, because they're not useful for us, and adjusted the geocoder position. I'm sure all this could be improved further when we move more controls into map panels (streetview, scheme context layer, basemap, etc)

Have gotten some good feedback about this, so will merge and iterate tomorrow when more people are around. Thanks for review
