POWRegistrationDisabled

sudo_set_network_pow_registration_allowed unconditionally fails because proof-of-work registration is deprecated and its toggle can no longer be changed. Nothing to check; the call is permanently disabled.

Declared by the AdminUtils pallet; it classifies to the semantic code disabled.
