fix(vtex): add searchField companion query params to List Orders

[guitavano]

Summary

• Uses schema override in download-schemas.ts to pull the Orders API schema from a fork with the fix, while waiting for vtex/openapi-schemas#1728 to be merged upstream
• Regenerates the Orders API SDK/types/zod with the corrected schema, adding:
  • searchField as an enum (sku_Ids, listId, tid, pci_tid, paymentId, nsu) instead of free-form string
  • 6 companion query parameters required for order filtering

Test plan

• bun test passes (77 tests, 0 failures)
• Server loads without errors
• Verify VTEX_LIST_ORDERS tool exposes the new parameters

Note: Remove the SCHEMA_OVERRIDES entry once vtex/openapi-schemas#1728 is merged.

Summary by cubic

Fixes VTEX Orders “List Orders” filtering by making searchField a strict enum and adding the required companion query params. Regenerates the SDK/types/zod using a temporary schema override until the upstream schema fix is merged.

• Bug Fixes

  • List Orders: searchField is now an enum (sku_Ids, listId, tid, pci_tid, paymentId, nsu) with matching query params added (sku_Ids, listId, tid, pci_tid, paymentId, nsu).
  • Adds a schema override in vtex/scripts/download-schemas.ts to pull the corrected Orders schema from a fork while the upstream PR is pending.

• Migration

  • When calling List Orders, use one of the allowed searchField values and include its matching parameter (e.g., searchField=sku_Ids&sku_Ids=11223).
