Use role 1 as default instead of 0 when assigning machines.

Since role 0 is illegal, setting the default role to 1 would reduce the number of clicks needed to get a machine up and running for huge UX stonks 📈

further random generated serial as default would also be nice, just to lazy -> click save rdy,
and if user like to change it, to his preference, than he is still able to do so.

Is this only UX or should it also be applied as role 1 by default in the backend of no other assignment exists. Need multiple devices for the same machine be assigned consecutive roles?

Role 0 is used by the Bus Coupler. Also it only shows roles that are available by the device. Should we really touch that? You can take a look into the linked branch, if that is even what we want.
