Fix #222: on_click callbacks now receive enum types instead of strings

- MouseButton enum (LEFT, RIGHT, MIDDLE, X1, X2) instead of "left", "right", etc.
- InputState enum (PRESSED, RELEASED) instead of "start", "end"
- Includes fallback to strings if enum creation fails
- Added proper reference counting for args tuple
