Clothing service fix (!407)

Server implementation of my `TraderServiceFix` mod.

Since 3.9 trader services were refactored by BSG. Resulting in them hard coding service ID's. This PR allows modders to push their trader ID to the `TraderConfig.moddedTraders.clothingService` array. It is then sent to the client where it adds it to the dictionary. I made this modular with its own interface in-case it needs expanded on in the future. So the this acts as both a fix and a groundwork for similar future fixes if need be as well.

Needs merged with https://dev.sp-tarkov.com/SPT/Modules/pulls/165
