stock: PCK/SHT fractional display, movement qty summing, import qty type

Display fixes:
- list_stock, list_movements, view_component: PCK stock divides by
  pack_size for fractional strip display; SHT shows 2 decimal places
- list_movements: pack_size fetched per component for PCK display
- All fractional formats use %.2f consistently

StockMovement::getList component filter:
- Replace INNER JOIN on xcmp with EXISTS subquery to avoid duplicate
  rows when a component appears multiple times in a movement BOM
- cmp_qty now SUMs all matching xref rows so multi-assembly RQs
  show total quantity rather than silently dropping duplicate rows

Movement BOM edit templates:
- stockmovement/edit_xref_bom_item.tpl: proper edit form for SGL/SHT/VOL
  lines linking back to view_component
- stockmovement/edit_xref_bompck_item.tpl: same for PCK with pack size hint

Import:
- ImportSimpleComponent: columns 6/7 (qty_type, qty_value) wired up;
  PCK/SHT/VOL writes qty xref so movement CSV imports pick up default type
