[ADD] sales:sell amazon fba products by serial or lots

[meval1006]

Added a new page detailing the "Kit" workaround developed by the support team to bypass the tracking Amazon FBA products via serial numbers/lots technical limitation.

Problem: When selling products tracked by Serial or Lot Numbers via Amazon FBA (Fulfilled by Amazon), Amazon's API does not send the specific serials or lots used for the sale. This crucial lack of information prevents the Odoo Amazon connector from validating the required stock move, consequently preventing the creation of the Sales Order (possibly blocking any other order, even if there is no lot).
