fix(web): cache server console context

[lyzno1]

Summary

• Cache the server console request context with React cache() for request-scoped dedupe.
• Preserve the existing server-only console transport and forwarded cookie/csrf behavior.

Verification

• pnpm -C web test -- service/__tests__/server.spec.ts
• pnpm -C web test -- app/(commonLayout)/__tests__/hydration-boundary.spec.tsx
• pnpm -C web test -- features/system-features/__tests__/system-features.spec.ts
• git diff --check

Manual Check

• Temporary server logging showed one / render previously called getServerConsoleClientContext() 3 times.
• After wrapping with React cache(), the same page render emitted one context log per request wave.
