[sameerasw]

This pull request introduces several UI improvements and new features to the AirSync Android app, primarily focusing on enhancing the user experience with new components and visual polish. The most notable changes include the addition of a floating media player, a slowly rotating app icon, improvements to splash and toolbar UI, and new app foreground detection logic.

New Features and Components:

• Added a new FloatingMediaPlayer composable, enabling a draggable, expandable mini media player with album art, media controls, and volume adjustment. This component provides a modern, interactive way to control media playback.
• Introduced a SlowlyRotatingAppIcon composable for a visually appealing, animated app icon, likely used in connection status or splash screens.

UI and UX Improvements:

• Updated the splash icon in MainActivity to use the Material You primary color as a tint, providing a more cohesive look with system theming.
• Increased the bottom spacer in the SettingsView for improved visual balance on larger screens.
• Commented out the navigation bar insets padding in AirSyncFloatingToolbar, possibly to address layout or overlap issues.

App Lifecycle and State Management:

• Added app foreground detection logic to AirSyncApp, tracking activity lifecycle events to determine if the app is in the foreground. This enables other components to query the app's visibility state.

Dependency and Version Updates:

• Incremented the versionCode in build.gradle.kts from 25 to 26, preparing the app for a new release.

Imports and Refactoring:

• Updated imports in ConnectionStatusCard.kt to support new UI features, including the animated app icon and additional Compose utilities. [1] [2]
