20260316f: Fix Cracker integrali default_qty (500→16) + detect absurd package sizes

- Fixed Cracker integrali default_quantity from 500 to 16 (was weight in grams, should be pieces)
- Review system now also flags products with absurd default_quantity (package size)
  e.g. a 'pz' product claiming 500pz per package gets flagged as '📦 Conf. sospetta'
- Uses same QTY_THRESHOLDS max values for detection
