[Feature request] Add warning if invalid address is entered into Owner address field

[ambassador000]

Although user would get an Alert message later in the process, it's possible to enter a Cold Staking Address in Owner address field without being warned it's invalid. This feature request is to make an obvious "invalid address" warning visible on the first look, just like it is showed in the 2nd picture below (for Cold Staking address). Even CS addresses are starting with different letter than Owner Addresses.

EDIT: Not sure why screenshot isn't showing color as expected, but it's a clear red colored outline showing an invalid address.
