feat: deploy go-fulfillr cases dashboard to home.debyl.io

- Bump fulfillr container image from 20260124.0411 to 20260509.1940
  (built from go-fulfillr commit 48b9f60 which adds /api/v1/cases
  endpoints for the contact-form CRM dashboard).
- Add fulfillr_cases_table default ("debyltech-cases-prod") so the
  HasCasesConfig() guard flips on at startup and the cases routes
  register.
- Add cases_table to production.json.j2 so it lands in /config inside
  the container.

Verified after deploy: GET /api/v1/cases returns the existing test
cases, PATCH succeeds, GSI1PK rewrite works.
