Emitted when total issuance is increased.

From Chain Metadata

Total issuance was increased by `amount`, creating a credit to be balanced.

Migration Notes

v424 v432 Breaking

amount changed from u64 to TaoBalance

Update decoders: SCALE encoding is positional, so any signature change (added, removed, or type-changed fields, or storage shape changes) shifts byte offsets and existing decoders will misparse this item. Re-derive types from the new metadata.
