Fix simulation_summary being called too often

[anisometropie]

• removing train_schedulev2 tag from postV2TrainScheduleProjectPath and making the endpoint a query (codegen made it a mutation by defaut as it is a POST)
• keeping train_schedulev2 postV2TrainScheduleSimulationSummary => the endpoint should but called again if one train is updated (more refinement to come Moving a train in space-time chart trigger simulation summary and projection unnecessarily #8010 ). It should not if a train is created/removed, but we can handle that manually with trainResultToFetch logic

closes #7989

Instead of changing the OpenAPI definition side, we can override the auto-generated providesTags/invalidatesTags here: https://github.com/OpenRailAssociation/osrd/blob/dev/front/src/common/api/osrdEditoastApi.ts

LGTM

We should maybe connect the trainResultToFetch state to the hook containing the summary endpoint to be sure that when we add a train, we fetch only the summary/getTrainSchedule of the new train and not the others that didn't changed.
Same when deleting a train.

Thank you for the changes. Regarding my last comment, we have fresh news.

A high priority issue has just came up. Most of the logic of timetable, simulation result will be changed (including trainResultToFetch) so don't bother to make these changes.

You just have the build to fix and we can approve this PR I think :)

[SharglutDev]

Lgtm, thank you !
