Update auto reactor shutdown circuit when docked to outpost to be more compact and reliable

Extended railgun forward so AI can use it. Updated reactor shutdown ciruit so it shutdown once docked to outpost (and only outpost). Fix invisible medbay hatch. Slightly nerf fuel consumption of reactor to compensate for speed.

Add label to toolbox to help make it clearer where spare tools are on sub.

Unhide reactor. Nerf normal speed to around 30km/h. At low overdrive, lights now have a chance to flicker.

Disabled reactor upgrades. Reactors values are required to be very specific for the overdrive to work right.

Wire the forgotten medfab & mark the decorative uranium fuel rod non interactable.

Update AI waypoints

Update gaps & water detector for better draining.

Updated the decon & fab again - no more side by side display with the cabinet
