- UpdateDnsRecords Action: controller method now one-liner, all DNS logic in Action with activity logging and edit lock. - Prometheus metrics at /v1/metrics: chain_height, alias_count, claims_pending, dns_tickets, gateways_live. Grafana-ready. - ValidateJsonRequest middleware: enforces application/json on POST, 64KB body size limit. Applied to all /v1/* API routes.
