* The method passes the NEW dates to getCurrentPrice() to ensure accurate

* NOTE: This method allows setting any dates, even if they're not available.
* Use the is_ready_to_checkout attribute to check if the dates are valid.

/**
* Get the current price with pool product inheritance support
* Get the current price with pool product inheritance support and cart-aware pricing.
*
* IMPORTANT: This method handles cart-aware pricing automatically!
*
* For pool products, this method:
* - Automatically retrieves the cart from session or authenticated user if not provided
* - Considers which price tiers are already used in the cart
* - Returns the next available price based on the pricing strategy (LOWEST, HIGHEST, AVERAGE)
*
* ⚠️ COMMON MISTAKE: Do NOT call getNextAvailablePoolPriceConsideringCart() directly!
* Always use this method instead, as it handles cart resolution and edge cases properly.
*
* Example usage:
* ```php
* ✅ CORRECT: Let getCurrentPrice handle cart resolution
* $price = $product->getCurrentPrice();
*
* ✅ CORRECT: Pass cart explicitly if you have it
* $price = $product->getCurrentPrice(null, $cart);
*
* ✅ CORRECT: Pass dates for booking calculations
* $price = $product->getCurrentPrice(null, $cart, $fromDate, $untilDate);
*
* ❌ WRONG: Bypasses cart resolution and session handling
* $price = $product->getNextAvailablePoolPriceConsideringCart($cart, null);
* ```
*
* @param bool|null $sales_price Whether to get sale price (null = auto-detect)
* @param mixed $cart Optional cart instance (auto-resolved from session/user if not provided)
* @param \DateTimeInterface|null $from Optional start date for booking calculations
* @param \DateTimeInterface|null $until Optional end date for booking calculations
* @return float|null The current price, or null if unavailable
