Subject: [PATCH] feat(protocol-dashboard): show validator stats from
 /health-check and link to /console

- Replaces the old uptime/disk/db health rows on the validator node page with stats parsed from the validator /health-check endpoint: Node Type, Peers (recursive count over nested groupings), Current Height, Storage Type, Last Restart (computed from timestamp - uptime), and Git SHA (short, full on hover).
- Adds a View Console button on the validator overview that opens ${endpoint}/console in a new tab.
- Drops the IndividualNodeUptimeChart section for validators only. Content/Discovery pages are unchanged.
- Guards the ServiceTable country flag against missing or non-ISO-3166 alpha-2 codes (validators may not report a country), rendering a neutral fallback.
