Allow multiple supplier/farmer entries per ingredient in batch origins

Each batch origin row now shows a searchable Rohstoff Select so the same
ingredient can appear in multiple rows with different suppliers or farmers.
Pre-fill from recipe still works (one row per ingredient); user clicks
'Eintrag hinzufügen' to add a second entry for the same ingredient.
