Add “Excel import” Button for CRUD Pages
Description: Add an “Excel import” button on CRUD pages generated by ABP Suite. Users can upload an Excel file to create new records or update existing ones.
Upload Excel file via UI.
Validate data (required fields, formats, etc.).
Show import results (created, updated, failed rows with errors).
Restrict access with permissions.
Additional Request: It would also be nice if the file generated by the "Excel export" button includes the tenant name (if triggered from a tenant instance) and the DateTime in the file name.
Example: Name_Tenant_DateTime.xlsx
