ZeroBalanceAfterWithdrawn

The withdrawal would leave a zero/non-viable balance; leave the existential deposit or transfer the remainder intentionally

Withdrawing TAO from the coldkey (e.g. paying a registration burn or adding stake) would leave the account at zero, below what keeps it alive. Check the coldkey's free balance and leave at least the existential deposit after the amount withdrawn.

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