feat(dealix): D0 launch hardening — DLQ, PostHog, circuit breaker, pricing, runbook
Close 6 critical launch gates for Primitive Launch Completion:

- DLQ (Dead Letter Queue): Redis-backed failure capture with retry drain
  and admin endpoints (/admin/dlq/queues, /admin/dlq/{queue}/purge)
- PostHog client: zero-dependency HTTP funnel tracker with 16 event types
  (landing_view → deal_won → payment_succeeded)
- Circuit breaker: in-memory fault isolation for external integrations
  with registry and admin status endpoint (/admin/circuit-breakers)
- Pricing router: 3-tier plans (Starter 990/Growth 2490/Enterprise custom)
  with Moyasar invoice checkout and webhook handler
- Config: added POSTHOG_API_KEY, MOYASAR_SECRET_KEY, DLQ settings
- Wiring: PostHog + DLQ initialized in main.py lifespan, pricing router
  in API router
- RUNBOOK.md: 5 incident scenarios (service down, DB down, LLM down,
  DB restore, version rollback)
- LAUNCH_GATES.md: 33-gate checklist across 7 categories
- 20 tests: all passing (DLQ 7, PostHog 4, circuit breaker 5, pricing 4)
