Replace HTML entities with Latin-1 bytes in UI strings

Replaced HTML-encoded German special characters with their Windows-1252 (Latin-1) encoded byte equivalents in user-facing strings in CatalogsGrid.razor and MassDataGrid.razor. Renamed and expanded the reset layout method for improved layout reset behavior. Updated button labels and info messages for consistency. These changes address encoding and rendering issues by shifting from HTML entities to direct byte encoding.
