fix: resolve GDScript type errors and warnings

- Fix Array[Card] type mismatch in move_generator.gd (rank_counts arrays)
- Fix shadowed variables in card.gd (create, from_packed parameters)
- Fix integer division warning in deck.gd (/ → //)
- Fix unused_signal warnings in event_bus.gd (per-signal annotations)
- Fix unused_parameter warning in audio_manager.gd
- Normalize whitespace in training_controller.gd
