Doors on all vehicles: no more part-logic FSMs in DoorSync, single sender for hinges

- DoorSync matched every FSM with door/hood/lid/trunk in its name, including
  the door parts' removal/assembly/bolt/paint FSMs and trigger_ objects, and
  forced their states at the other players: doors hung crooked, snapped back
  or came off. Those are excluded now (assembly runs via FsmSync).
- HingeSync: on a parked vehicle everyone nearby sent the angle, so doors
  ping-ponged. Now only the player who clicked near the door (4 s) sends;
  on a driven vehicle the driver sends; received angles are held 3 s.
