lmr: time window for possible simulations is incorrect

[maelysLeratRosso]

What happened?

Now : one can start a simulation with a departure between J+1 17h and J+7 (anytime), no matter when the simulation is done.

What did you expect to happen?

The expected behavior is :
Before 17h, one can start a simulation between J+1 and J+7 (anytime for both)
After 17h, one can start a simulation between J+2 and J+7 (anytime for both)

How can we reproduce it (as minimally and precisely as possible)?

On which environments the bug occurs?

Recette (SNCF)

On which browser the bug occurs?

Ideas

handle this in osrd-data

pros

• Quick and dirty

cons

• Shady backend feature
• We have to decorrelate basic caching and stdcm search env change since we don't know basic caching duration (between 20min and 1h)
• probably too much logic in private code for a feature that should be public

handle this in editoast

pros

• history of search envs
• no need to change osrd-data logic
• strong resilience to the switch 16h59 -> 17h
• end of stdcm search env with 1 row table in editoast datamodel

cons

• more complexity

✅ We decided solution 2 is better.

Refinement

Adapt GET /search_env and POST /search_env:

• GET:
  • Take the env that is in the enabled env and if there are multiple just take the newer.
  • If no env is enabled then take the most recent enabled_to
• POST: keep it stupid
  • Just check enabled_from < enabled_to
  • in dev mod set enabled_* in the past and far future

Migration:
Set the dates of enabled_* in the past, if there is only 1 env this one will be picked with the fallback logic.

osrd-data

Change the calls to POST /stdcm_search_env with the correct enabled_*
