refactor!: enforce that scopes contains CAIP-2 chain IDs

[danroc]

This PR updates the type of the scopes property in the KeyringAccount type to restrict it to CAIP-2 chain IDs.

The motivation for this change stems from CASA reserving the 0 chain reference of the eip155 namespace for EOA accounts (i.e., eip155:0:<address>), eliminating the need to support namespaces in KeyringAccount.
