Server component render error on /money-flow and /economy/health endpoints

Resolved. The SSR render errors on /money-flow and /economy/health were the max_statement_time exceeded 500s — fixed this cycle by the shared-Redis SWR cache (PAR-156, incl. caching /economy/health which was uncached), the money-flow streaming-pivot rewrite that brings it under the statement timeout (PAR-157), and the probe/restart-cascade fix. Verified live: both routes return 200 (/money-flow ~0.16s, /economy/health ~0.06s).
