Refactor Tray composable for consistent visibility handling

Introduce a `showTray` variable to standardize Tray visibility logic across all demos. This ensures proper recomposition when `alwaysShowTray` changes and adds explicit state binding for checkable items (e.g., "Always show tray" and "Hide on close"). Simplifies and improves the code's maintainability and clarity.
