MSCO 2.10.2: passenger only while moving, drain plug sync, admin VEHICLE tab, profile layout

- Passenger: auto ride-along only when the vehicle moves (speed from its motion, also for
  kinematic remote cars) - no more getting stuck while working in the engine bay or re-captured
- Bolts with a function (drain plug: stage 0-5 = oil leak on) are synced as stage and applied
  through the bolt's own stage logic; world authority sends its state once after joining.
  Fixes endless oil leaking when players had the drain plug in different states
- Admin menu VEHICLE tab: fluids with FILL/EMPTY, all Database parts with wear/damage,
  REPAIR/BREAK per part, REPAIR ALL, filter
- Server profile: info and players as two equal cards, no wrapping
- fsmdump also lists FSM variables
