bugfix(audio): Fix particle cannon being inaudible after saveload

[stephanmeesters]

• Closes Particle Cannon Sound is not audible after saveload #2023

Fixes issue where sound from the particle cannon is not audible after saveload.

Tested with savegames in scenarios

• STATUS_FIRING -- actively firing
• STATUS_POSTFIRE -- beam is in decay
• STATUS_PACKING -- beam has decayed, cleaning up

Adds sound handles for m_firingToIdleSound which is the sound at the particle cannon itself, and m_annihilationSound which is the sound of the beam.

Todo

• Replicate to Generals

Greptile Overview

Greptile Summary

Restores particle cannon audio after save/load by re-registering sound handles in loadPostProcess() when the cannon is in STATUS_FIRING, STATUS_POSTFIRE, or STATUS_PACKING states.

• Adds sound handle restoration for m_firingToIdleSound (cannon sound) and m_annihilationSound (beam sound)
• Mirrors the existing pattern used in setLogicalStatus() at ParticleUplinkCannonUpdate.cpp:1239-1242 and createOrbitToTargetLaser() at ParticleUplinkCannonUpdate.cpp:1052-1056
• Properly checks conditions before registering: sound event name must be non-empty, and for beam sound, beam drawable must exist

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The fix follows established patterns from the same codebase, properly checks preconditions, addresses a specific bug with clear reproduction steps, and only affects save/load behavior without changing runtime logic
• No files require special attention

Why POSTFIRE and PACKING ?

Can you explain how the statuses relate to the lifetime of the 2 sounds?
