feat(admin-performance): fix RSS measurement, add multi-worker aggregation, and new dashboard panels
- Fix RSS metric: replace peak `ru_maxrss` with current RSS via `process_rss_mb()`
- Add `query_snapshots_aggregated()` with SQLite time-bucket GROUP BY to eliminate
multi-worker zigzag oscillation in trend charts
- Add Worker Memory Guard panel (GaugeBar + 6 StatCards) to dashboard
- Add Pareto Materialization panel (stats grid + fallback reasons table)
- Fix Redis memory trend to display in MB instead of raw bytes
- Restore 14 accidentally deleted migration JSON config files
- Fix 44 pre-existing test failures: mock targets, redirect expectations,
filter params, navigation baselines
