Add a stream of mark price inputs to the mark price header

[JonRay15]

The Chore

In the header

That mark price is now actually being driven by various inputs from the mark price config as per #5809.

Some people might want to see the stream of prices that are driving that.

These can be found here: https://vega-data.nodes.guru:3008/api/v2/market/data/4e9081e20e9e81f3e747d42cb0c9b8826454df01899e6027a22e771e19cc79fc/latest

Under here:

"markPriceType": "COMPOSITE_PRICE_TYPE_MEDIAN"
"markPriceState": {
"priceSources": [
{
"priceSource": "priceFromTrades",
"price": "59293800000",
"lastUpdated": "1709116382757832435"
},
{
"priceSource": "priceFromOrderBook",
"price": "59236121590",
"lastUpdated": "1709117299204118135"
},
{
"priceSource": "priceFromOracle1",
"price": "59188643715",
"lastUpdated": "1709117257770320896"
},
{
"priceSource": "priceFromOracle2",
"price": "59188643715",
"lastUpdated": "1709117257770320896"
},
{
"priceSource": "medianPrice",
"price": "59188643715",
"lastUpdated": "1709117297885735065"
}
]
}

it would need to also pullin the composite price type.

Example 1 - Median

• Price Type: Median
• Trade price: A
• Book price: B
• External price 1: C

Example 1 - Weighted average

• Price Type: Weighted average
• Trade price: A (20%)
• Book price: B (30%)
• External price 1: C (50%)

Note those weights are not available on the marketData API so you will need to grab them from the markets API in the same way as we do on #5809

I could imagine these on a tooltip popup similar to what we do for liquidity

Additional details / background info

Can we look at the configs in mainnet currently and determine if there is something understandable we can show that explains these more clearly?
