Ability to stake AZERO directly from Common

From a user point of view, Aleph Zero is the same, so from Aleph Zero's point of view, it's not helpful to view staking, trading and other AZERO activities as different parts of the user's journey.

Integrating the AZERO staking dashboard to Common would ensure continuous journey and linkage between azero trading and azero staking.

Buy AZERO from Common and stake directly; or unstake AZERO from Common and use it to trade!
