Added "Update dynamic theme logic for Android 12+ and Android 11-" - da13bec

Updated the "Enable dynamic theme" functionality to handle different Android versions appropriately:

Android 12+ (API 31+):

• Hide "Color Palette" option in AppearanceSettings when dynamic theme is enabled
• Use system's dynamic color scheme from wallpaper when no song in queue
• Extract colors from song thumbnail when song is playing

Android 11 and below (API 30-):

• Always show "Color Palette" option regardless of dynamic theme setting
• Use the Color Palette selection when no song in queue (cannot access wallpaper colors)
• Extract colors from song thumbnail when song is playing

Files Changed:

1. AppearanceSettings.kt - Updated visibility condition for Color Palette option
2. MainActivity.kt - Updated theme color selection logic to check Android version

Both files already had the necessary android.os.Build import, so no additional imports were needed.

thanks!
