fix: avoid using any for MediaQueryListEvent return type

[ysdede]

🎯 What: The code health issue addressed was the use of any as the return type for the MediaQueryListEvent handler dprChangeHandler in src/components/LayeredBufferVisualizer.tsx.
💡 Why: Replacing any with void improves code health by tightening the TypeScript types, accurately reflecting that DOM event handlers do not utilize return values, and preventing potential accidental misuse.
✅ Verification: Verified by running the test suite (bun test) to ensure no regressions were introduced. Additionally, performed frontend verification using a Playwright script to confirm that the UI compiles and runs smoothly, preserving existing behavior.
✨ Result: A safer, more strictly typed event handler signature with no change to runtime functionality.

Code Review

This pull request correctly improves type safety by changing the return type of the dprChangeHandler event handler from any to void. This is a good practice as event handlers typically do not have a return value, and this change makes the code more robust and easier to understand. The change is isolated and has been implemented correctly.
