Pre-merge author checklist

I've followed MetaMask Contributor Docs and MetaMask Extension Coding Standards.
I've completed the PR template to the best of my ability
I’ve included tests if applicable
I’ve documented my code using JSDoc format if applicable
I’ve applied the right labels on the PR (see labeling guidelines). Not required for external contributors.

Pre-merge reviewer checklist

I've manually tested the PR (e.g. pull and build branch, run the app, test code being changed).
I confirm that this PR addresses all acceptance criteria described in the ticket it closes and includes the necessary testing evidence such as recordings and or screenshots.

Note

Medium Risk
Touches transaction submission payloads sent to Smart Transactions and relay services; while additive, it can affect downstream API validation/analytics expectations if mismatched with backend/controller versions.

Overview
Smart Transaction submissions now include an additional metadata.client field alongside txType for batch, pre-signed, and fee-signed flows.

EIP-7702 relay submissions (delegation-7702-publish) also attach the same client identifier, derived from platform (Firefox vs Chrome) via a new smart-transaction/utils.ts helper and new shared constants. The PR also upgrades @metamask/smart-transactions-controller to ^22.3.0.
