make it a dedicated stats modal, not under account (#4627)

## Description:

seperates the stats modal into a dedicated path, with gameID support
e.g. :

#modal=stats&gameID=VvyXpL9x

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory

## Please put your Discord username so you can be contacted if a bug or
regression is found:
