Fix a bunch of html UI's for 516 (#88917)

## About The Pull Request
Moved broken on 516 UI's to browser datum
They now work and have a dark theme
Most of them are admin ones (All except 1)

I tried to check all the raw HTML UI's by typing `<< browse(` into the
VSC search and going through each element, but I might have missed
something.

What worked as it was, I didn't touch, except for the Dynamic control
UI's

## Why It's Good For The Game
Admin can do their things on 516
Coders/Mappers can debug some stuff on 516
