fix(StatusBaseButton): correct radius and icon size for `isRoundIcon` mode

- this fixes 2 small regressions, namely in how we calculate the
background corner radius and icon size when in the mode of `isRoundIcon`
- the "Saved addresses" button in wallet's left view is very special on
its own; overall we have only 2 instances of this "round" icon buttons
in the whole app

Fixes #16156
