DB

• Setup cascade delete: deleting a user also deletes their settings (note: this action is not exposed in the API)

API

• It seems that the /auth/users/{user_id}/settings endpoint accepts empty strings in the SLURM accounts array: slurm_accounts: [""]

Task-collection and job-execution API

• Let's add slurm_accounts: list[str] to the required and validated settings, both for sudo and ssh slurm backends

Checklist before merging
