## **Description**

This update upgrades the asset controllers to version 60, which
introduces important changes to the `TokensController`:

- Refactored `TokensController` to eliminate reliance on a single
selected network ([#5659](MetaMask/core#5659)).
- `TokensController` methods now require `networkClientId` to be
explicitly passed as a parameter.
- Token management logic is now fully parameterized by `chainId`,
enabling multi-chain token handling and improving reliability across
network changes.
- Internal state updates and token metadata fetching are now scoped to
the appropriate `chainId`.
