Checked one value, stored another
Products loaded from the supplier's CSV file crash with TypeError: '<' not supported between instances of 'str' and 'int', and products created in code end up with SKUs like ' spo-11681' even though the SKU check passes. Fix Product.__init__ so it tidies and converts every value, checks the tidy values, and stores exactly what it checked.
