Kunthawat Greethong 8b84378fe1 feat: SaaS foundation for CrowdSight
Elevate MiroFish/CrowdSight from single-container dev to a SaaS foundation:

- Local memory backend (Zep-compatible): memory services/models, local graph
  builder + updater, AgentActivity seam, import-boundary isolation; Zep stays
  default, local is opt-in behind MEMORY_BACKEND. Semantic parity not yet proven.
- Durable product persistence: projects/simulations/reports schema (migration
  0007) + tenant/owner-scoped ProductRepository + dual-write + scoped_project
  read-first + ArtifactStore abstraction; durable JobQueue + worker.py.
- SaaS hardening: durable RateLimiter (wired to login), UsageService (LLM
  accounting), redacted AuditService, idempotency, CORS allowlist, safe API
  errors, single-use PasswordResetService + endpoints (covers invite-pending).
- Exactly 3 roles (super_admin/admin/user) with tenant authz policy.
- Admin UI: GET/POST/PATCH /api/admin/users + GET/PUT /api/admin/settings
  (super-admin only, encrypted/masked); AdminView.vue + SettingsView.vue with
  admin/super-admin route guards, th/en i18n.
- Production deploy topology: multi-stage Dockerfile (frontend build + gunicorn
  wsgi + nginx SPA-proxy + supervisord worker), backend/wsgi.py, gunicorn dep.

Backend 197 passed; frontend 10 tests + build green. ruff unavailable (gap).
No commit of credentials; secrets handled via env/.env.example.
Deferred: Zep semantic A/B parity, object storage cutover, mobile QA, EasyPanel
container build of deploy topology.
