Add-on price (RTC-27290)

Items, models and variants from offers with mix type 100 are exported in the Excel file with the 'add-on price' value. Items can be also imported via Excel file with 'add-on' price. 'Add-on' cannot be smaller than 0 and greater than 999999. If 'add-on' field is empty in the Excel file, it's not updated for already added items and it's set to 0 for new items in the offer.

Performance for dynamic segments (RTC-27540)

• The method GET ItemSegmentations/GetItemsWithPrices [id] returns results faster, there's no timeouts when requesting prices (if they are, they're related to bug in Promotion that will be fixed in: RTC-27395 [Promotion] Add indexes to the views)
• Method return top price for an item (in list)
• The hierarchy for returning prices when making promotion is (the same):
  • When filtering by store - store price, with fallback to profile and then price zone.
  • When filtering by team - Price zone price with fallback to store.
  • When filtering by profile - Price zone price with fallback then store.
  • When no filtering (promotion on all stores)- Price zone price -> profile -> store. 

Fix: Valid to in the past (RTC-26811)

'Valid to' cannot be set in the past when creating a promotion. Validation message is displayed under the 'Valid to' field.
