[BUG] Allow AvailableModelsResolver to Authorize by Project
What does this MR do and why?
When Duo features are set to "Off by default" on a root group, it has a cascading effect that also disables Duo on its projects. To re-enable Duo in the project, a user can enable the GitLab Duo toggle under Project > Settings > General > GitLab Duo.
Due to a bug in AvailableModelsResolver (a dependency of the model selection feature in the chat window), this was not working correctly. The resolver was set up for handling root namespaces only so when a chat window opened in a project context, it would return an auth error.
This MR fixes the issue by allowing the resolver to handle a project resource and perform its auth check on it accordingly.
