fix: Consent Page app name

[jonas-martinez]

About this PR

Closes https://github.com/lenra-io/server/issues/527

This was just a bug in the way we match on the env_id. As you can see in this PR, there was a is_binary check on the environment but this could never match because the env_id is an integer.

I change the is_binary to a is_integer and now this works properly.

How to test my changes

You can run the app-molny with a local setup of the server using this branch and you will see on the consent page that the app name is properly displayed.
