Add radio and checkbox selector hover and pressed states

This is a nice to have for a filing like this that is rarely used but it could be more important for components that other teams might be re-using when we move other filings to nuxt (perhaps like the share structure)

- Add the hover, focused or pressed states for checkboxes and radio button selectors
- Radio buttons are visible on staff payment component
Checkboxes to update

- Shares: special rights or restrictions checkbox
- Court order section: Plan of arrangement checkbox
- Director Address form: Same as Delivery Address
- Certify Checkbox

Design Ticket #29897

Start with Design Ticket #29897 and review the listed checkbox locations plus the staff payment radio buttons. Compare their current selector behavior and identify the relevant frontend entry points. Done means the specified radio and checkbox selectors visibly support hover, focused, and pressed states across those components.
