Create ESC from the Dashboard

[iszulcdeepsense]

we made a new ESC in dev, but this new user does not appear in the list of Auth subjects.

Auth subject wasn't created for ESC. That's wrong. I checked that it gets created only if an ESC is created by an API endpoint POST /api/v1/escs, but if it's done manually in the Admin panel, then the Auth subject model is gone and has to be created manually too.

I guess we need a new Dashboard page for managing ESCs to make it less surprising and to use the proper endpoint under the hood.

Shouldn't we actually be thinking of taking what we use the Django dashboard for and reflecting it in the RT dashboard, in general?

Yes. Django was a good kick starter. Common use cases should be in the dashboard after all. Now it's a good time for this, especially with the #480 on the horizon.
