Code Review

This pull request introduces a new Android sample application, MediaQuerySample, which demonstrates how to use the ExperimentalMediaQueryApi in Jetpack Compose for building adaptive UIs. The sample includes a dashboard that reacts to device posture, input peripherals, and hardware sensors. Feedback suggests removing several unused imports and redundant @OptIn annotations throughout MediaQueryDashboard.kt. Additionally, it is recommended to refactor the layout logic to reduce code duplication and to replace LocalConfiguration with the mediaQuery API for retrieving device orientation and dimensions to maintain consistency with the sample's purpose.

Thanks for creating the sample. I left some comments. Please take a look at them.
