Add condition for trigram and operational_point in pathSteps

[SharglutDev]

Description and goal

For the pathfinding, we can pass as input either a step as uic, trigram, operational_point (id) or track/offset. In most of the app we check for uic or track/offset but not for the rest. It can lead to some issue when we import timetable with a .json which can have these type of values.

Acceptance criteria

Harmonize the use and check of all PathItemLocation types.
