Duplicate a module

Sets the display order of the submodules and lessons placed directly in the module. The `ids` array accepts both module public IDs (`mod_`) and lesson public IDs (`les_`) in the desired order. The array must contain the complete set of BOTH direct submodules and direct lessons currently in the module. Omitting a kind is allowed only when that kind has no items; otherwise the entire request is rejected. The request requires at least one ID; an empty array is rejected. Positions are assigned independently within each kind, starting at 1, so interleaving IDs does not assign one global mixed ranking. For example, with only lessons [les_1, les_2], sending [les_2, les_1] sets their positions to 1 and 2. With both kinds present, sending only lesson IDs is rejected. If the supplied set does not match, the API returns the `order_set_mismatch` error code and the existing order remains unchanged. To avoid overwriting concurrent changes, send the module `ETag` from the retrieve operation in the `If-Match` header. Discover the required set through GET /products/{product_id}/modules/{module_id}/content, following every cursor page without narrowing filters such as status, kind or search. A fully paginated list is still limited by credential visibility; verify that the credential can read the entire required set before reordering. On order_set_mismatch, re-read the set and check scope and visibility instead of blindly retrying stale IDs. The response returns the complete reordered collection in a single response, including collections larger than 200 items. This reorder response is not paginated.
