[x] Make rootnet completely without burn (currently it will still burn on the registration)
[x] Remove stake from the registration. So the only operation that the registration does is decrease stake on burn from balance, keep it simple and safe
[x] Make sure set_max_allowed_uids can not deregister modules (!Make sure the 820 maximum limit still stays)
