Create new Type to show DEX tag in summary header

[Ilyak777]

Right now we don't have a specific type to show DEX public tag in Summary Header - we need to add it

It should look like this -

                "market": {
                    "type": "dexTag",
                    "value": {
                        "meta": {
                            "bgColor": "#FF007A",
                            "tagIcon": "https://blockscout-content.s3.amazonaws.com/uniswap.png",
                            "tagUrl": "https://uniswap.org/?utm_source=Blockscout",
                            "textColor": "#FFFFFF",
                            "tooltipDescription": "Trade crypto and NFTs safely on the top DeFi platform. Swapping made simple. Buy and sell crypto on Ethereum, Base, Arbitrum, Polygon, and more.",
                            "tooltipTitle": "Uniswap",
                            "tooltipUrl": "https://uniswap.org/?utm_source=Blockscout"
                        },
                        "name": "Uniswap V2",
                        "ordinal": 1,
                        "slug": "uniswap-v2",
                        "tagType": "protocol"
                    }
                }
