Until now, ntfy metrics could only be collected by an external Prometheus
server. Enabling the integrated Prometheus (`prometheus_enabled: true`)
now also has it scrape ntfy, like it does for the other services.

The upstream Synapse Grafana dashboard uses `{{job}}-{{index}}` in its
legends to tell workers apart, but the worker scrape configs only set
instance, worker_id, job and app labels. Without an index label, the
dashboard legends collapsed and workers could not be distinguished.
Derive the index label from the worker id (its per-type index is the
first number in the id, e.g. federation-sender-1, stream-writer-2-events),
matching the index label already set on the main process target.
