[grade=A] DC-068: Fix all 3 ESLint errors + auto-fix warnings

- Removed orphaned __trace2.js (unnecessary escape error) - Fixed empty block statement in config-migrations.test.js busy-wait - Fixed empty block statement in metrics.test.js busy-wait - Auto-fixed 5 fixable warnings via eslint --fix - Remaining 547 warnings (require-await, no-unused-vars) are non-blocking code quality - 0 errors, 1633 tests pass

+/**
+ * DC-083: Branch coverage tests for the new /system/health endpoint in routes/health.js.
+ *
+ * The endpoint at GET /api/system/health aggregates four checks (services, memory,
+ * diskSpace, incidents) into an overall status. It has many uncovered branches:
+ *  - status === 'ok' / 'degraded' / 'down' in the services check
+ *  - status === 'ok' / 'warning' in the memory check
+ *  - status === 'ok' / 'warning' / 'critical' in the diskSpace check
+ *  - status === 'ok' / 'degraded' in the incidents check
+ *  - each check has a try/catch → unknown fallback
+ *  - overall status computation (unhealthy / degraded / healthy)
+ *
+ * Also covers additional uncovered branches in the /health-checks/* endpoints:
+ *  - unhealthy filter in /health-checks/status
+ *  - incidents open/non-empty
+ *  - incidents/history with pagination params
+ *  - /health/probe with and without ?url
+ *  - /health/services with array vs object services data, error paths
