feat: finish multi-pin pickup end-to-end; fix checkout-datetime followups
Multi-pin pickup selection (study §3.4) — previously a standalone unused
endpoint + TODO comments:
- app/services/pickup-locations.server.ts: pure filterPickupLocationIds +
  I/O resolvePickupLocations (active + has a PICKUP slot template +
  ProductRule allowedLocationIds + inventory exclusion).
- resolveAvailabilityRequest returns pickupLocations[] on method=PICKUP and
  defaults the active location to the first eligible pickup point.
- apps.scheduling.locations.tsx refactored onto the shared resolver
  (was a second copy of the logic).
- Storefront widget: pickup-location chooser (name + address, optional
  multi-pin Google map) when >1 eligible point and none block-configured;
  picking one re-requests availability for that location. New styles +
  widget.choose_pickup_location locale (en + fr).
- Checkout extension Checkout.jsx: same chooser before the date list.
- tests/unit/pickup-locations.test.ts (5 cases); suite 161 green.

checkout-datetime follow-up fixes from the 808a3b7 review:
- typescript devDep ^7.0.2 -> ^5.6.3 (there is no typescript@7 on npm).
- Deleted dead shopify.d.ts (Preact-global shim, unused after the React
  rewrite) and dropped it from tsconfig include.

Also stages the CLI-written `uid` lines in the checkout-datetime and
payment-customization extension tomls.

payment-customization

Shopify Function (cart.payment-methods.transform.run) that hides cash-on-delivery / pay-in-store payment methods when the shopper's chosen fulfillment method is SHIPPING (study §5.2 parity).

Pure decision logic lives in src/evaluate.js and is unit-tested at the repo root (tests/unit/payment-customization.test.ts) with plain Vitest — no WASM build needed for that.

Before first build / deploy

schema.graphql and generated/ are not committed (they're produced by codegen and gitignored, same as the other Function extensions). Run:

npm --prefix extensions/payment-customization run typegen

to pull the API schema and regenerate generated/api.ts, then shopify app deploy picks it up. The extension also needs the write_payment_customizations scope, which shopify.app.toml already requests, and the merchant must activate it under Settings → Payments → Payment method customizations in the admin.
