fix(blackbox): the driver's valve as its gauge shows, no clash of the traction's labels, fewer self-made events

- The pressure of the driver's valve is named as what its gauge shows
  (the equalizing reservoir, the FV4a's time reservoir), alike in both
  languages.
- The traction's values are clipped to their columns, and the torque
  converter's label is shorter: it ran into the oil pressure's.
- The doors in two columns, the radio's label shorter: the names were cut.
- The compressor and the motor fans go on and off by themselves: no
  events for them.
- The summary of HeadCodes.Right back above it.
