Fixing withdraw modal updates and adding info

[IanWoodard]

Removed refetching for balance result data as it would often conflict with the max withdrawable data which would make things complicated. I chose to remove it rather than try to make it work as a constantly flowing stream of data makes keeping the form up to date while not messing with the user's input very complex. Moreover, I find it annoying when my balances are constantly changing, especially when trying to withdraw everything. I know there are some workaround we could try, but unless there are clear drawbacks to this approach, I feel it would be better to keep it simple. Additionally, I added a callout if the user is limited in how much they can withdraw due to utilization. To determine if the user is limited, I took a similar approach to the isConstrainedByUtilization by checking the withdrawablePercentage.
