[Overlapping] Improve market price input #2

[Costa769]

• edit price - do not default into price field when price is available
  flow:

1. click edit price
2. IF external price is available, do not default into the price field (because it force to show the last bit of the price which is usually a number that doesnt make sense)

• edit strategy with no external price
  flow:

1. edit a strategy with no external price
2. show the price input modal

3. in the place where we typically show "use market" and allow users to click and use the external market price, replace it with "use strategy" and allow users to click and use the strategy geomean(marginal.sell, marginal.buy)
4. add tool tip when mouse over "use strategy" with this text: "This price is the geometric mean of the strategy buy and sell marginal prices."
