PA control box part detection fix (#24356)

PA control box part detection fix (#24356)

* * Fixed rounding errors when the PA control box was checking for parts, sometimes leading to the obscure "port/starboard emitters are not detected".
* Auto-rotated the PA control box toward the fuel box when checking for parts
* Swapped the wired/completed state sprites for the PA control box as it appears they were inverted

* Update Content.Server/ParticleAccelerator/EntitySystems/ParticleAcceleratorSystem.Parts.cs
