- introduce StatusButton storybook page with controls to play around
with the its options and variants
- StatusBaseButton: make the content item horizontally centered by
default
- StatusBaseButton: remove `textAlignment` and fix `textFillWidth` for
the intended usage
- fixup usage of the 2 above options which were introduced merely as a
workaround, mostly in wallet + corresponding storybook pages
