Fix random spawn (#2958)

## Description:

"You can pick your spawn in random spawn games in v29. You need to open
the menu and click on the attack button. That's it."

Thats the fix for this problem.
Radial menu no longer allows to attack (pick a spawn) while random spawn
is enabled.
And SpawnExecution got a check so you cannot send malicious intents.

## 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
- [X] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

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