Replace the customers/data_request, customers/redact, and shop/redact
stubs with real logic in app/services/gdpr.server.ts: compile a
customer's Booking history, anonymize customerEmail/customerPhone on
redact, and purge every shopDomain-scoped row on shop uninstall
(Booking before Location, relying on Location's cascade for
SlotTemplate/SlotOverride/BlackoutDate/Zone/Rate). Covered by a new
tests/integration/gdpr.test.ts against live Postgres to verify the
FK deletion order actually works, not just typechecks.
Still commented out in shopify.app.toml pending Protected customer
data access approval in the Partner Dashboard — unrelated to code
readiness.
