fix: revert investigative changes, keep root cause fixes only

Reverts diagnostic instrumentation and defensive hardening added during memory leak investigation. Only root cause fixes survive. Root causes fixed: - SQLite driver: auto-finalize wrapper + PRAGMAs - WS routers: delete clientConfigVersions on disconnect (unbounded Map leak) - WS private router: same + Redis key cleanup Reverted: - Memory monitor, rate limiting, request timeouts (diagnostic/hardening) - shutdownAuditLogger wiring, audit re-queue change, debug logs (cleanup/secondary) - package-lock.json drift
