Fix for v30: do not show "Not logged in" on flag modal on CrazyGames (#3631)

## Description:

Fix for v30 and main.

Do not show "Not logged in" on the FlagInputModal in CrazyGames, since
our own login should not work there. It was added in
https://github.com/openfrontio/OpenFrontIO/pull/3521 in v30 so this fix
is needed for production too.

## Please complete the following:

- [x] I have added screenshots for all UI updates

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
