Ensure the fresh PVC is writable by the pod’s non-root user.

job-queue-pvc uses the gp3 storage class and mounts at /app/data. The pod defines runAsNonRoot but no fsGroup or explicit runAsUser. If the provisioned filesystem is root-owned without write permission for the runtime UID, ssh-keygen fails and the container exits before the service starts. Provide an ownership or permission mechanism through the OpenShift deployment, or restore an appropriate fsGroup.

In `@deploy/job-queue-service.yml` at line 48, Update the deployment security
context for the pod mounting /app/data so its non-root runtime user can write to
the fresh job-queue-pvc volume; configure an appropriate fsGroup or equivalent
OpenShift ownership mechanism while preserving runAsNonRoot and the existing
ssh-keygen startup flow.

Validate the complete SSH key pair.

If /app/data/nebius-ssh-key exists but its .pub file is missing, the startup check succeeds. With NEBIUS_ENABLED=1, NebiusInstanceManager then fails while reading the missing public-key file. A stale or mismatched public key can register a different key from the one later used for SSH.

Derive the public key from the validated private key and atomically replace the .pub file before starting uvicorn. This also rejects a corrupt private key before the service starts.

In `@deploy/job-queue-service.yml` around lines 47 - 50, Update the SSH key
initialization block before uvicorn starts to validate the private key, derive
its public key from that validated key, and atomically replace
/app/data/nebius-ssh-key.pub. Ensure startup fails for a missing or corrupt
private key and never proceeds with a stale or missing public key; preserve the
existing failure behavior for unsuccessful key operations.
