Identity overrides don't work in offline local evaluation mode

Empieza en flagsmith/flagsmith.py, en la ruta de carga del manejador offline alrededor de la línea 117 y en la ruta de actualización de la API alrededor de la línea 273; sigue cómo se representan identity_overrides en el archivo local. Verifica que la evaluación local offline aplique el override para el identificador 146433, manteniendo el comportamiento normal del estado de las funcionalidades, y añade o ejecuta cobertura de regresión para este caso.

I'm using version 3.8.0 and have identity overrides enabled for my environment.

I'm using a copy of a config for local development and initialize Flagsmith as follows:

local_file_handler = LocalFileHandler(
    environment_document_path=f"./feature_flags_configuration.local.json"
)
flagsmith = Flagsmith(
    environment_key=settings.FLAGSMITH_API_KEY,
    enable_local_evaluation=True,
    offline_handler=local_file_handler,
    offline_mode=True,
)

I have following settings on my config:

  "feature_states": [
    {
      "feature": {
        "id": 103972,
        "name": "ipqs_geo_ip",
        "type": "STANDARD"
      },
      "enabled": true,
      "django_id": 576867,
      "feature_segment": null,
      "featurestate_uuid": "04dcc7d5-b387-4668-8264-d30a2da2e111",
      "feature_state_value": null,
      "multivariate_feature_state_values": []
    }
  ],
  "identity_overrides": [
    {
      "identifier": "146433",
      "environment_api_key": ...,
      "created_date": "2024-08-26T17:45:31.959128Z",
      "identity_features": [
        {
          "feature": {
            "id": 103972,
            "name": "ipqs_geo_ip",
            "type": "STANDARD"
          },
          "enabled": false,
          "django_id": null,
          "feature_segment": null,
          "featurestate_uuid": "964dd1e9-b34a-4bf7-9984-937abbba3f0e",
          "feature_state_value": null,
          "multivariate_feature_state_values": []
        }
      ],
      "identity_traits": [],
      "identity_uuid": "8fd6de03-b834-41d2-b5ec-7076d00e6cd3",
      "django_id": null,
      "composite_key": "cfWNJQwEQkcAiKxSPFL2rv_146433"
    }
  ],

However, identity overrides are ignored unless I disable offline mode.

The root cause must be that it is updated only here when API request is made and are not loaded from offline handler here.

In production, I'm also using the local file as a fallback for the case when Flagsmith is unavailable during app start, so it might become a problem in production in rare cases.
