feat(Python): establish proper inheritance hierarchy for UI types
All UIDrawable-derived Python types now properly inherit from the Drawable base class in Python, matching the C++ inheritance structure. Changes: - Add Py_TPFLAGS_BASETYPE to PyDrawableType to allow inheritance - Set tp_base = &mcrfpydef::PyDrawableType for all UI types - Add PyDrawable.h include to UI type headers - Rename _Drawable to Drawable and update error message This enables proper Python inheritance: Frame, Caption, Sprite, Grid, and Entity all inherit from Drawable, allowing shared functionality and isinstance() checks. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
