Duo doesn't work on project if the instance set it off by default
Summary
If self-managed instance set Duo disabled by default, Duo doesn't work on project where it's enabled.
Environment
I reproduced this bug for self-managed GitLab with my GDK
Steps to reproduce
- Go to Admin->GitLab Duo and change configuration to be Off by default.
- Go to any project where your user is Owner, go to Settings->General and search for Duo settings, make sure that it's enabled.
Bug
There is no Duo Chat window, or if it exists (rare case), I can't ask any question and got an error that AI isn't enabled.
Expected behaviour
I can use Duo Chat. With Duo enabled by default on instance level, everything works correctly.
