### Description

The entire section of the Bisq market section (with the exception of the make/take offer screens) does one of the following:

- Does not display deviation from market price
- Shows market price but combines it with trade price

It would be a lot more useful for traders if the all the Bisq market section does the following:

- Shows market price as a separate value

This would make it a lot easier to look at historical trades and see what  deviation from market price they were made at (Market > Trades)

I also think by keeping market price as a separate value in Market > Offer Book > Buy / Sell BTC it would make the offers more clear.

#### Version

v1.5.9

### Steps to reproduce

- Go to `Market > Trades` look at prices what price from market deviation was achieved? You will be unable to tell.
- Go to `Market > Trades` then Download a CSV, look at prices what price from market deviation was achieved? You will be unable to tell.
- Go to `Market > Offer Book > Buy BTC` price from market deviation is included after the trade price (not as clear as it could be)
- Go to `Market > Offer Book > Sell BTC` price from market deviation is included after the trade price (not as clear as it could be)


### Expected behaviour

- Go to `Market > Trades` look at prices what price from market deviation was achieved? You will be able to tell and sort by deviation.
- Go to `Market > Trades` then Download a CSV, look at prices what price from market deviation was achieved? You will be able to tell and sort by deviation.
- Go to `Market > Offer Book > Buy BTC` price from market deviation is included in a separate column. 
- Go to `Market > Offer Book > Sell BTC`  price from market deviation is included in a separate column.
