fix(app): Do not allow Argo-CD namespace access by default when app in any namespace restrictions exist

[OpenGuidou]

Fix part of #20820.

With the current behavior it is not possible to restrict the usage of the Argo CD namespace when using the App in any namespace feature. This PR contains changes that should allow the current behavior when no restrictions are in place, and allow to blacklist the controller namespace if desired.

The new behavior should be quite sound but I can wrap it with a feature-flag if required.

I'd like this to be cherry-picked to 2.13 as well.
