feat(server): persist server self-metrics into ClickHouse

Browse Source 
Snapshot the full Micrometer registry (cameleer business metrics, alerting
metrics, and Spring Boot Actuator defaults) every 60s into a new
server_metrics table so server health survives restarts without an external
Prometheus. Includes a dashboard-builder reference for the SaaS team.

### Server Self-Metrics
The server snapshots its own Micrometer registry into ClickHouse every 60 s (table `server_metrics`) — JVM, HTTP, DB pools, agent/ingestion business metrics, and alerting metrics. Use this instead of running an external Prometheus when building a server-health dashboard. The live scrape endpoint `/api/v1/prometheus` remains available for traditional scraping.
See [`docs/server-self-metrics.md`](./server-self-metrics.md) for the full metric catalog, suggested panels, and example queries.
