Improve bid with DAI UI

[LukSteib]

Goal

The bid with DAI flow doesn't show unintuitive numbers

Context

In the light of recent auctions we experienced our UI to display unintuive numbers.
Let's first investigate how we ended up in this situation; what numbers are actually displayed and then improve it by either not showing numbers any more or showing them in a better representation

Assets

• The 15k number with the "AND" in the minimum leftover is unintuitive
  • why do we display the chost parameter here in the first place?

Tasks

• Rethink the logic for the numbers we display in the min leftover row of the Bid with DAI tx page
• Propose a change to make it more intuitive
• Implement the change
