Implement LED test effects with proper cleanup

- Add LED test effects page with multiple test patterns (solid colors, rainbow, breathing, flowing)
- Implement Rust backend for LED test effects with proper task management
- Add automatic cleanup when navigating away from test page using onCleanup hook
- Ensure test mode is properly disabled to resume normal ambient lighting
- Clean up debug logging for production readiness
- Fix menu navigation issues by using SolidJS router components

Features:
- Multiple test patterns: solid colors, rainbow cycle, breathing effect, flowing lights
- Configurable animation speed
- Automatic cleanup prevents LED conflicts with ambient lighting
- Responsive UI with proper error handling
