[powergrid_usecase] Using a larger environment creates a corruption error.

[ahmerique]

When using a large environment (in development), I had a corruption error after this line
if self._stop_if_anticipation_security_analysis(f_obs, f_env, contingency_line_ids)

Steps to reproduce:
I made a standalone script to reproduce the bug.

• git clone my fork
• follow the standard installation of the usecase example (no need to install interactiveAI)
• activate venv
• run python standalone_bug.py
• There should be a critical error on step 52 or above : a double free or corruption (!prev)

Clues:

• The large environment introduces the concept of alerts, this happens after an alert happen. So it might be linked to an incompatible f_obs and lightsim2grid.SecurityAnalysis
