Prioritize explicit PI ref over PHOTON_INHERIT

[noble-ux]

Ideal Behaviour

Vehicles with the following code should pull a predefined PI config if available: HasPhoton = true, Photon = "PHOTON_INHERIT"

Actual Behaviour

Currently this script will prevent a photon config from using a predefined PI config. Currently this code actually needs to be removed in order to utilize the PI config without referencing it directly as seen below: HasPhoton = true, Photon = "sgm_fpiu20"

Not a bug? Intended behaviour is to leave blank with those. Registered PI isn't indexed by model, so that can't be used automatically pulled.

We can move it around so explicit PI ref (table or name) > default > inherit

Partial documentation issue, but ideally PI lighting would always be set to on when a model with a referenced PI is being used.
