New App Icon and Animated Splash Screen

App Icon: Replaced default Android robot with the new "Cinephile" clapperboard design. Splash Screen: Integrated androidx.core:core-splashscreen library. Animation: Created animated_clapperboard.xml featuring a continuous 360° spin. Styling: Updated Splash background color to Lavender (#FDF7FF) to match design requirements. Scaled down the animated icon (0.6 scale) to improve visual balance. Logic: Updated MainActivity.kt to handle installSplashScreen() and added a 1-second delay to ensure the animation plays fully before the app loads. Manifest: Cleaned up unused namespaces and configured the Theme.App.Starting theme.
