Fix button focus styling

[DS123-ally]

Description

Fixes the persistent dark state on the Next button after it is clicked.

Fixes #7940.

The shared button styling applied the same dark background to both :hover and :focus. After a mouse click, the button retained focus, so it stayed visually dark until focus moved elsewhere. This made the button look inactive or disabled.

This change keeps the dark styling on hover only and adds a :focus-visible outline so keyboard users still get a clear focus indicator.

After

The first section shows the original issue: the Next button remains dark after click. The final section shows the fixed behavior: the button returns to its normal yellow state immediately after click.

Validation

• Ran .\node_modules\.bin\eslint.cmd src\reusecore\Button\btn.style.js
• Ran git diff --check
• Verified the behavior with a local before/after browser test page

📝 Walkthrough

Walkthrough

The button styles separate hover behavior from focus behavior. Focus-visible buttons receive an offset active-color outline. Other focus states suppress the outline.

Since this PR is intentionally self-contained and shouldn't depend on #7960 merging first, could the button's :focus-visible style use the same theme.secondaryColor / 3px focus treatment introduced in #7960? This would keep #7962 independently mergeable while maintaining a consistent keyboard-focus indicator across the site.
