auctionTypeCar

[andronisdre]

• [x] add fields present in new ER diagram
• [x] add auctionId referencing
• [x] add DTO for auctionTypeCar
• [x] implement DTO to different postman functions. For example, GET ALL should show carDTO type instead of auctionTypeCar type
• [x] make it so that the field "AuctionModels auction" has to be unique, try @Indexed(unique = true) annotation for that.
• [x] make it so that when you create an auctionTypeCar, the auction that is referenced has its field "isActive" set to true and save the auctionModel.
• [x] think if anything more is needed
• [x] do we need to change the filtering by price, brand etc methods that are related to auctions?
• [x] test everything in postman
