The `StatusRoundButton` was missing the `hoverEnabled` flag, causing it
to not turn the cursor into a pointer when the component is hovered.
It's also not rendering the proper hover color.
This commit fixes that to improve usability and look & feel.
Update StatusRoundButton colours to support a "tertiary" style (background and icon color overlay), as well as tertiary hover colour.
Fix the modal header close button so that it more closely matches the design.
Replace the buttons in the onboarding modals with StatusRoundButtons were possible.
As per discussion, there's no "primary" and "secondary" type in round buttons.
They just appear in different sizes (44x44, 40x40, 32x32). The size determines
their look & feel
