fix: Add eslint ignore for shadcn component utility exports

- Added eslint-disable-next-line for react-refresh/only-export-components
- Badge and Button components export utility functions (badgeVariants, buttonVariants)
- These utilities are required by shadcn pattern for variant composition
- Suppressing warning is appropriate since this is intentional design
