+feat(rest): `GET /api/v1/data/:object/export?template=true` answers an xlsx import template for the object (#18386)
+
+Clause-②: yes (widening)
+
+The export door takes one more query parameter, `template`. `template=true`
+answers an `.xlsx` workbook with no data rows; `template=false`, or no
+`template` parameter, answers the export exactly as before, byte for byte.
+
+- **Columns.** The fields an import stores: every field of the object except
+  those marked `system`, `hidden` or `readonly`, and `formula`, `summary` and
+  `autonumber` fields, in the order the object declares them. The seven columns
+  the platform adds to every object (`organization_id`, `created_at`,
+  `created_by`, `updated_at`, `updated_by`, `owner_id`,
+  `owning_business_unit_id`) are never template columns. A field the caller's
+  field-level security does not let them read is left out. An explicit
+  `?fields=` list is used as sent.
+- **First sheet.** The header row, with ` *` after each field that is required
+  and has no default value, and one example row to replace or delete. Select,
+  radio and boolean columns carry a dropdown.
+- **Second sheet.** One row per column: the field's API name, its type, whether
+  it is required, and the values the import accepts for it.
+- **Language.** The sheets are in Chinese for a `zh` request locale
+  (`?locale=` or `Accept-Language`) and in English otherwise.
+
+The same two permission checks as the export apply: an object that does not
+expose export answers `405`, and a caller without the export permission answers
+`403`. `template` with a value other than `true` or `false`, a `format` other
+than `xlsx`, or any of `limit`, `page`, `filter`, `search`, `searchFields`,
+`orderby` or `header` beside `template=true`, answers `400 VALIDATION_ERROR`.
