AccountRejectsLockedAlpha

Locked alpha was being transferred to a coldkey whose AccountFlags do not have the accept-locked-alpha bit set, e.g. during a lock transfer or coldkey swap of locks. Check the destination coldkey's AccountFlags storage and have the recipient opt in to receiving locked alpha before retrying.

Declared by the SubtensorModule pallet; it classifies to the semantic code invalid_argument.
