[Frontend] Art Item Auction

[CahidArda]

We will add art item auction support to our platform. In order for this to happen, we need to include the following functionalities:

• [x] (Owner) Artist shall be able to start an auction. This will be done on the art item page. There will be a button next to the auction status information. Only shown to the owner artist.
• [x] Users shall be able to make bids for the art item. This will again be on the art item page.
• [x] (Owner) Artist shall be able to stop the auction.

I have finished the auction implementation. Here is how it works:

State space of the display is 2x2, dimensions being on_auction and max_bid (whether any bid was made). There are 2x2=4 different states.

State 1: Initial State (not on auction, no bid)

User creates and art item and views the page:

Users other than the owner doesn't see the new auction display at all.

State 2: Auction Starts

Owner clicks the start auction button and auction starts:

Other users:

Visitor users:

State 3: First Bid Made

Steve enters a bid amount and makes the bid. Owner:

Steve:

Visitor users:

State 4: Auction ends

Owner clicks end auction button to end the auction. He can restart the auction if he wants.
