Handle vehicle spawning and deleting commands on the server

Description

The /car [vehicleModel] & /dv commands will now spawn and delete entities using exclusively server-side logic. This improves security and compatibility with the sv_entityLockdown strict mode.

The car command is cool but the dv i'd still like the functionality of deleting the closest vehicles too as it does now
