[FIX] pms_api_rest: keep folio-level pricelist on folio modification

[DarioLodeiros]

On folio modification through the external API (PUT /folios/external), OTAs send the pricelist at folio level while the reservation payload may omit it. update_folio_values never wrote folio.pricelist_id and wrapper_reservations only read the reservation-level pricelistId, so reservations re-created by a modification kept the original (stale) pricelist instead of the rate sent in the modification (e.g. a booking switched to a non-refundable rate stayed flexible).

Fix

• Update folio.pricelist_id on modification when the incoming folio-level pricelist changes.
• Use the folio-level pricelist as a fallback for reservations that don't carry their own pricelistId, symmetric with the create flow.

Reproduced from real API request logs of an OTA modification.
