Change default parameter values based on testing experience and outside input

[rowgraus]

What is the Problem Being Solved?

Parameter values defaulted til now for testing include some values that aren't intended to be suitable for production usage. This ticket covers changing those parameters, specifically in:

Vault Manager

• Changes to align with initial Gauntlet recommendations until the EC is able to make its own independent determination

Auctioneer

• Change Auction operational parameters to align with design previously communicated to the community - specifically around the price lock period and the minimum discount (65%)
