[Bug]: Last vehicle max speed isn't said to be clamped

[jostephd]

Version of OpenTTD

jgrpp-0.63.0-2-g73dbed7e2

Expected result

The "Max speed of last vehicle" should say "643 km/h", or at least "more than 256 km/h".

Actual result

It says "Max speed of last vehicle: 256 km/h".

That's confusing, because that's not the speed limit of any relevant piece of infrastructure (engine, wagons, track).

Steps to reproduce

1. Set the Station ratings tooltip preference to Detailed.
2. Get a Lev4 maglev train to pick up cargo at a station and leave the station.
3. Wait a few seconds for that station to get a cargo rating for that cargo.
4. See what the cargo rating tooltip says.

This is how the ratings algorithm works, the speed field for this is one byte. The details mode is to display what is recorded and goes into the algorithm.
There isn't any plan to record additional information or make fields wider just for the tooltip.
