fix(ui) : show type name and ref in slot selects, stay on page after save

- PieceSelect, ProductSelect, ComposantSelect: show type name and
  "Ref." prefix in dropdown descriptions (matching create page format)
- Category edit pages (component, piece, product): stay on page after
  successful save instead of navigating back to list
- Component and product edit pages: same — stay on page after save
