Add satellite splash sound and fix asteroid crash sounds

[wannerdev]

Description

Enhances audio feedback by adding distinct sounds for different collision types and fixing asteroid crash sound behavior.

Changes

• Added Satellite and Asteroid imports for entity type checking
• Satellites crashing into sun now play warning sound (splash effect)
• Asteroids crashing into sun play no sound (silent disappearance)
• Asteroid-satellite collisions now properly play crash sound
• Fixed asteroid swarm parent entity being skipped for sound
• Improved collision sound logic with entity type detection
• Using warning_sound as placeholder for splash effect

Sound Behavior

Before:

• All collisions except sun collisions: crash sound
• Sun collisions: muted (no sound)
• Asteroid swarm parent: skipped

After:

• Satellite → Sun: Warning sound (splash effect)
• Asteroid → Sun: No sound (silent)
• Satellite ↔ Satellite: Crash sound
• Satellite ↔ Asteroid: Crash sound
• Asteroid swarm parent: Properly skipped

Audio Assets

• Currently using warning_sound as placeholder for splash effect
• Can be replaced with custom splash sound asset later
• Crash sound properly plays for non-sun collisions

Benefits

• Better audio feedback for different collision types
• Satellites entering sun have distinct sound
• Asteroids silently disappear into sun (less audio clutter)
• Improved player awareness of collision types
• More polished audio experience

Testing

• Launch satellite into sun → Verify warning/splash sound plays
• Launch asteroid into sun → Verify no sound plays
• Crash satellites together → Verify crash sound plays
• Crash satellite into asteroid → Verify crash sound plays
• Check that sounds don't overlap or cause audio issues
