Pull request overview

This PR updates the Android blur overlay behavior to react to device UI mode (light/dark) changes, and simplifies the React Native-side downscaleFactor handling while updating documentation/examples accordingly.

Changes:

• Android: Make overlay color resolution UI-mode-aware and refresh overlay color on configuration changes.
• React Native: Remove downscaleFactor scaling logic and refactor how ref is passed to the native Blur component.
• Docs/examples: Update TypeScript ref examples and adjust Android platform notes.
