Issue #3589220: Add missing schema for the displays (Attach to) option on excel_export

Frank Mablyrequested to merge
issue/xls_serialization-3589220:3589220-add-missing-schema into 2.1.x

Summary

ExcelExportDisplayTrait::defineOptions() adds a displays option to the excel_export display plugin (the standard "Attach to" sequence), but the schema for views.display.excel_export did not declare it. Configuration Inspector reports a "missing schema" row on every view that uses this display.

Adds the same displays mapping views.display.data_export uses upstream.

Risk

Schema-only change, zero runtime behaviour impact.

Test plan

  • Pipeline passes.
  • After applying the patch, Configuration Inspector returns no errors for the excel_export display (modulo the per-site integer-vs-string artefact on displays.default, which clears on a re-save and is documented in the issue).
