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.
