* Add status server and metrics tracking with live status page

- Add `swanlake-core/src/metrics.rs` for query/update latency, slow query, and error tracking
- Add status HTTP server (`/` and `/status.json`) via Axum in `swanlake-server/src/status.rs`
- Expose metrics and session registry snapshots on the status page
- Add related config options: `SWANLAKE_STATUS_ENABLED`, `SWANLAKE_STATUS_HOST`,
  `SWANLAKE_STATUS_PORT`, `SWANLAKE_METRICS_SLOW_QUERY_THRESHOLD_MS`,
  `SWANLAKE_METRICS_HISTORY_SIZE`
- Update `CONFIGURATION.md` with new status/metrics env vars
- Wire up metrics to query/update handlers and session registry

* Replace status page with new HTML dashboard

- Add `swanlake-server/src/status.html` with a modern, dark-themed status dashboard for live
  metrics, sessions, latency, slow queries, and errors.
- Update `swanlake-server/src/status.rs` to load the HTML from the new file using `include_str!` for
  easier editing and maintenance.

* Add status.json endpoint check to integration tests

* Add status page docs and update status.html with logo and polish
