Emits the **total** akava amount for both ukava and akava send/mint/burns. If both akava,ukava are sent (not possible via x/evm nor cosmos messages but still an edge case), then the sum is emitted. No other denoms are emitted by x/precisebank as they will be emitted by the underlying x/bank
Implement GetBalance for extended balances which passes through to `x/bank` for non-extended denoms. This diverges from `x/evmutil` behavior which will panic on non-"akava" calls.
Add bank / account keeper mocks for testing, with mockery config for [mockery package setup](https://vektra.github.io/mockery/latest/migrating_to_packages/)
