E2E Test Selection:
The changes are narrowly scoped to:

1. Adding a new money = 'Money Keyring' entry to the ExtendedKeyringTypes enum in app/constants/keyringTypes.ts.
2. Adding ExtendedKeyringTypes.money to the KEYRING_TYPES_SUPPORTING_7702 list in account-supports-7702.ts, enabling EIP-7702 (Setup Smart Account / gas fee token) support for Money keyring accounts.
3. A corresponding unit test.

SmokeMoney: Directly relevant — the new Money Keyring type is clearly tied to the MetaMask Card/Money product. This change enables EIP-7702 features for Money keyring accounts, which could affect card-related transaction flows.

SmokeConfirmations: The accountSupports7702 function is used in transaction controller initialization to gate EIP-7702 features (batch transactions, gas fee token payments). SmokeConfirmations explicitly tests EIP-7702 account abstraction features. Enabling EIP-7702 for a new keyring type could affect confirmation UI behavior for Money keyring accounts.

No other areas are impacted — there are no changes to UI components, navigation, core Engine initialization, account management, or network handling that would warrant broader test coverage. The keyringTypes.ts file is imported by many files, but the change is purely additive (new enum value) and only the account-supports-7702.ts file uses the new money value.

Performance Test Selection:
The changes are purely additive — adding a new enum value and including it in a small array check. There are no UI rendering changes, no new data loading paths, no state management changes, and no impact on app startup or critical user flow performance. No performance tests are warranted.
