Formatting-only changes across all component and story files.
No logic or behaviour changes — only whitespace, line breaks, and trailing commas.

Button:
- Add aria-busy={loading} for assistive technology
- Add visually-hidden "Loading" text for screen readers
- Mark CircularProgress as aria-hidden (decorative)
Card:
- Add tabIndex={0} and role="button" when interactive
- Fix Record<string, any> → Theme type for type safety

- Reserve 2px border on all cards (transparent for elevated, coloured
for outlined) so selected state only changes colour, not width
- Add 150ms ease-in-out transitions for border-color and background-color
consistent with Button/Input interactive timing
- Remove borderWidth/borderStyle from selected sx (now handled by theme)
