Function IsValidMxNWindowId

Modules/RESTAPI/src/mitkRenderingController.cpp:1523–1526

* \brief True if `id` matches the canonical MxN window-id pattern from the * OpenAPI spec (`^[A-Za-z][A-Za-z0-9.-]*__[A-Za-z0-9_.-]+$`). * * Mirrors the `MxNWindowName` parameter pattern in `openapi.json` so that * malformed ids are rejected at the controller boundary with 400 * INVALID_REQUEST, before any UI-thread dispatch. Well-formed but unknown * ids fall through and

   * ids fall through and surface from the bridge as 404 RENDER_WINDOW_NOT_FOUND.
