Update app launcher icon and enable release build optimizations

This commit updates the app's launcher icon assets and modifies the build configuration.

Key changes:

- **Launcher Icon Update:**
    - Added new foreground launcher icon assets (`ic_launcher_foreground.webp`) for different screen densities (mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi).
    - Updated existing `ic_launcher.webp` and `ic_launcher_round.webp` assets.
    - Added a Play Store icon (`ic_launcher-playstore.png`).
    - Created `app/src/main/res/values/ic_launcher_background.xml` to define the launcher icon background color as white (`#FFFFFF`).
    - Updated `mipmap-anydpi-v26/ic_launcher.xml` and `mipmap-anydpi-v26/ic_launcher_round.xml` to use the new color resource for the background and reference the new foreground mipmap. The monochrome drawable reference was removed.

- **Build Configuration (`app/build.gradle.kts`):**
    - Enabled `isMinifyEnabled = true` and `isShrinkResources = true` for release builds to optimize the APK size.
    - Refined the logic for enabling ABI splits: `isEnable = project.findProperty("splitApk")?.toString()?.toBoolean() == true`. This ensures `isEnable` is explicitly true only if the property is "true".
