<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Dependency bump to a new major version of
`@metamask/assets-controller` and updates to the AssetsController
messenger event surface could affect asset updates on network add/remove
flows.
> 
> **Overview**
> Updates the app to use `@metamask/assets-controller` `^7.1.2` (from
`^6.2.1`), with corresponding `yarn.lock` changes.
> 
> Aligns the AssetsController messenger typing and delegation to include
the new `NetworkController:networkAdded` and
`NetworkController:networkRemoved` events, and updates the associated
unit test expectations.
> 
> Adjusts the test `initial-background-state.json` asset identifiers to
use checksummed token addresses in the `AssetsController.assetsInfo`
keys.
