/**
* Test to reproduce and fix the production bug where:
*
* Pool (default price: 5000) with 6 singles:
* 1. price: 50000
* 2. price: none (should fallback to pool price 5000)
* 3. price: none (should fallback to pool price 5000)
* 4. price: none (should fallback to pool price 5000)
* 5. price: 10001
* 6. price: 10002
*
* When adding 7 items to cart, expected:
* - 3x 5000 (from singles 2,3,4 using pool fallback price) = 15000
* - 1x 10001 (from single 5) = 10001
* - 1x 10002 (from single 6) = 10002
* - 1x 50000 (from single 1) = 50000
* Total: 85003
*
* But actual was:
* - 7x 5000 = 35000
*
* Also: CartItems from/until and price/subtotal should be updated by cart->setDates
