* Separate artifact and metadata cache metrics on /metrics and the analytics page
* Serve metadata cache stats from a shared snapshot and split Grafana cache panels by kind
- Track per-caller request and byte counts in a bounded table
- Export proxy_client_requests_total and
proxy_client_response_bytes_total over a closed label set; addresses
are never labels
- Gate the sources card behind ui_request_sources, off by default,
since /ui carries no authentication of its own
- Move access_log.trust_forwarded_for to a top-level key
- Keep remote as the TCP peer and add remote_ip alongside it

- 33 panels, no hardcoded data source UID
- Three ecosystem variables, because the label means three different
things across /metrics: the package record, the request path, and
the handler's own name
