fix(android): resolve icon generation and build script errors

Fixed Android build issues that were preventing successful builds:
- Updated icon generation script to create proper adaptive icons without
  referencing missing drawable files
- Changed log_warning function call to log_warn in build script
- Icon generation now creates foreground mipmap files and proper XML configs
- Build process successfully generates all required Android assets

Resolves "export: production).=: not a valid identifier" error and enables
successful Android builds with automatic resource generation.
