Standardize Python API constructors and remove PyArgHelpers
- Remove PyArgHelpers.h and all macro-based argument parsing - Convert all UI class constructors to use PyArg_ParseTupleAndKeywords - Standardize constructor signatures across UICaption, UIEntity, UIFrame, UIGrid, and UISprite - Replace PYARGHELPER_SINGLE/MULTI macros with explicit argument parsing - Improve error messages and argument validation - Maintain backward compatibility with existing Python code This change improves code maintainability and consistency across the Python API. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
