fix: add overflow hidden to code group containers for corner radius clipping

[patcapulong]

Summary

• Adds overflow: hidden !important to the general .code-group, [data-testid="code-group-select"] CSS rule in mintlify/style.css
• Fixes sharp corners and border clipping on API reference code blocks in production, where Mintlify's Tailwind overflow-hidden class is no longer being applied to code group containers

Context

The content-area scoped rule (#content .code-group, etc.) already had overflow: hidden, but the general selector used by API reference pages did not. Without it, inner elements with border-radius: 0 bleed through the parent's rounded border, making corners appear sharp.

Test plan

• Verified the fix resolves the issue in production (via browser dev tools)
• Confirm code blocks on API reference pages render with rounded corners after deploy
• Confirm code blocks in content pages (guides, quickstarts) are unaffected

Greptile Summary

Adds overflow: hidden !important to the general .code-group, [data-testid="code-group-select"] CSS rule to ensure proper corner radius clipping on API reference code blocks. The content-area scoped rule (#content .code-group) already had this property, but the general selector used by API reference pages was missing it, causing child elements with border-radius: 0 to bleed through the parent's rounded corners.

• Fixes visual bug where code group containers displayed sharp corners on API reference pages
• Aligns general selector behavior with content-area scoped rules that already use overflow: hidden
• Single-line CSS change with no side effects

Confidence Score: 5/5

• This PR is safe to merge with no risk
• Single-line CSS addition that mirrors existing pattern already used elsewhere in the file. The property is standard, uses !important flag consistently with surrounding rules, and fixes a specific visual bug without introducing any behavioral changes
• No files require special attention
