fix(ui): prevent copy button overlap with language label in code blocks (#2533)

## Summary - Fixed UI element occlusion bug where the "Copy" utility button was unusable due to layout overlap with the language identifier label in code blocks - Added flexbox properties (gap, items-center, truncate, min-w-0, flex-shrink-0) to ensure proper spacing and prevent overflow ## Test plan - Open a chat with code blocks containing language labels (e.g., typescript, javascript) - Verify the language label and copy button no longer overlap - Test with narrow window widths to ensure the layout remains correct - Click the copy button to confirm it's clickable and functional Fixes #2466 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- <a href="https://app.devin.ai/review/dyad-sh/dyad/pull/2533" target="_blank"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://static.devin.ai/assets/gh-open-in-devin-review-dark.svg?v=1"> <img src="https://static.devin.ai/assets/gh-open-in-devin-review-light.svg?v=1" alt="Open with Devin"> </picture> </a>   --- ## Summary by cubic Fixes an overlap in code blocks where the Copy button covered the language label, so the button stays visible and clickable at all widths. Fixes #2466. - **Bug Fixes** - Aligned header padding with pre (left/right 0, px-6) and added gap-2/items-center for spacing. - Applied truncate and min-w-0 to the language label to prevent overflow. - Set the Copy button to flex-shrink-0 to avoid shrinking. <sup>Written for commit 246b0df6569b41f813f0843b048125da8efe9830.
