Add initial stock load importer and improve import results template

load_stock.php creates a pending StockMovement IN from a 3-column CSV
(component_title, desc[ignored], qty), then ?process=y commits via
processMovement(). import_results.tpl now shows movement status and
the ?process=y hint when a pending movement is waiting.
