[FIX] product_sale_price_from_pricelist: Correct _compute_price method signature

- Changed parameter from 'qty' to 'quantity' to match Odoo 18.0 base class
- Fixes TypeError: ProductPricelistItem._compute_price() got an unexpected keyword argument 'quantity'
- This was causing price calculation failures when saving sale orders

[FIX] website_sale_aplicoop: Fix logging format string

- Changed logging format from %d to %s for existing_draft_id which is a string from JSON
- Fixes 'TypeError: %d format: a real number is required, not str' in logging
