fix: add named port 'http' to vin-decoder Service and container for ServiceMonitor compatibility

The ServiceMonitor at flux/vin-decoder/servicemonitor.yaml references port
by name ('http'), but the Service had anonymous port 80 -> 3000 and the
container had no named port. Prometheus ServiceMonitor port matching requires
the port name to match between the Service and the ServiceMonitor spec.

Adds:
- name: http to the containerPort (port 3000)
- name: http to the Service port (port 80 -> targetPort 3000)

This allows the kube-prometheus-stack ServiceMonitor to correctly scrape
/metrics from vin-decoder pods.

Closes leeworks-agents/api-company#174
