Installed Operators page only lets project admin delete CSV

When listing installed operators, we attempt to list subscriptions in all namespaces in order to associate subscriptions/csvs. This prevents users without cluster scope list priveleges from seeing subscriptions on this page, which makes the uninstall action unavailable.

Always

1. Install an namespaced operator
2. Log in as a user with project admin permissions where the operator was installed
3. Visit the installed operators page
4. Click the kebab menu for the operator from step 1

The only action available is to delete the CSV

The "Uninstall Operator" and "Edit Subscriptions" actions should show since the user has permission to view, edit, delete Subscription resources in this namespace.
