Enhance CMake configuration and improve string safety in source files

- Updated CMakeLists.txt to silence C++23 deprecation warnings and added definitions for intrinsic int128 support.
- Modified GitHub Actions workflow to handle missing asset directories gracefully and ensure correct versioning in Info.plist.
- Refactored string handling in multiple source files to use std::memcpy for safer string copying, preventing potential buffer overflows.
- Improved font loading logic and ensured consistent handling of theme properties in the editor.
