Cosmos address conversion

[Kouteki]

Description

As a Cosmos token holder ISBAT check whether I have any GNOT tokens allocated on Independence Day.

Acceptance Criteria

• When I submit a Cosmos address, it's converted from the cosmos prefix to the g prefix before querying the gno.land account balance

Misc

Depends on #3899 and #4061
