[FIX] stock_declared_value: move_line.product_uom → product_uom_id (v19 compat)

In v19 the field stock.move.line.product_uom was renamed to product_uom_id.
Four accesses in stock_declared_value/models/stock_picking.py still used the
old name on move_line recordsets (stock.move.line), causing AttributeError
when the _compute_declared_value method runs.

Note: move_line.product_uom_qty (a distinct Float field) was NOT renamed —
it keeps the same name in v19 and is left untouched.
