Subject: [PATCH] Enhance Catalogs grid UI and filter row experience

Added custom CSS for sortable headers and search inputs. Replaced default filter row inputs with styled DxTextBox components. Set default sort on "Id" column and disabled sorting for action column. Updated grid to use new catalog-grid styles.
