Fixes 7 pre-existing failures in test_entity_renderer tests:
- ColorRect → Sprite2D cast; .color → .self_modulate for D-033 color checks
- Position offset: (TILE_SIZE-24)/2 → EntityRenderer.ENTITY_OFFSET_{X,Y} (0.0)
- Rotation accuracy: expected values updated for raw un-normalised Godot rotation
Also adds SoundIndicatorRenderer to global_script_class_cache.cfg so test_rendering.gd parses.
