Prevent multiple clients from using the same account (#706)

## Description:

This change blocks a persistent ID from being reused by more than one
client in the same game. This setting is only enabled in staging and
prod.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors
