Update test demos for new Python API and entity system

- Update all text input demos to use new Entity constructor signature
- Fix pathfinding showcase to work with new entity position handling
- Remove entity_waypoints tracking in favor of simplified movement
- Delete obsolete exhaustive_api_demo.py (superseded by newer demos)
- Adjust entity creation calls to match Entity((x, y), texture, sprite_index) pattern

All demos now properly demonstrate the updated API while maintaining their
original functionality for showcasing engine features.
