Note

Medium Risk
Dependency-only change, but it upgrades a transaction/payment controller that can impact transaction submission and fee/payment behavior at runtime.

Overview
Bumps @metamask/transaction-pay-controller from 16.3.0 to 16.4.0, updating both package.json and the corresponding yarn.lock resolution/checksum.
