front: take into account new flag for using speed limits

[axrolld]

The idea is to make front end keep this flag when it is present (from a json import for example), and keep its default value otherwise. Not adding anything in the interface.

Fixes #10858

You can test with this trainschedule:

• import the trainSchedule, change the rollingStock for a TGV and see that the train can hit 300km
• change in the json the option usingSpeedLimits, import again the trainSchedule, change the rollingStock for the same TGV. The GEV should not be the same
• check that you can't create a train which will not use the speed limits:
  • click on edit on the train which does not use the speed limits
  • close the manageTrainSchedule page immediately and create a new train
  • the new train should use the speed limits

lgtm, thank you 🙏

LGTM :)

Nice catch ! I remove the field from the persist config, so it is not persisted anymore and if a user opens a new tab, the config will have usingSpeedLimit = true

looks good to me, just wait @SharglutDev to resolve :)

Was waiting for @clarani to rebase but I ended up rebasing in local to test :)
