More granular roles for the Currents dashboard

Currently, the ability to create and modify Currents Actions (such as skipping or quarantining tests) is limited only to users with the Admin role. However, this Admin role also grants access to sensitive areas like team management and billing details.

It would be ideal to have a role that can create & manage Currents Actions but cannot modify any organisation/team or billing-related details, so some kind of Test Manager role. Such separation would help us delegate test management responsibilities more effectively while maintaining appropriate access controls for administrative functions.
