Can't toggle remaining models on space when a model gets disabled at organization level

[axelander]

Issue

Model A and B are enabled for an organization. A space in the org has both of the models enabled. When model A is deactivated for the organization, you can no longer toggle any of the other models on/off on the space.
The setter for completion/embedding models on the space-model validates that the space can access the model (https://github.com/inooLabs/intric-release/blob/main/backend/src/instorage/spaces/space.py#L202-L218), which it no longer can.

Would it make sense to remove the setter validation to allow spaces to keep settings for currently inaccessible models?

Example test that verifies the behaviour

    """
