Implement Premium Theme-Aware Adaptive Icon

- Migrated launcher icon from static drawable to modern Adaptive Icon architecture
- Implemented dynamic backgrounds: Tokyo Night Storm for Dark Mode, Tokyo Night Day for Light Mode
- Processed foreground layer with proper safe-zone padding to prevent clipping
- Generated legacy mipmap icons for compatibility with older Android versions
- Updated LatinIME.java to use the new mipmap icon reference
- Removed deprecated drawable icon assets
