fix(snaps): Adjust SnapUIAccountSelector height

[GuillaumeRx]

Description

This PR adjust the size of the SnapUIAccountSelector to avoid squishing the content when the account has a label.

I also included a small fix to disable the hover background color of the AccountListItem.

Fixes:

Manual testing steps

1. Enter two SRP in the extension
2. Use the Account Selector in Snaps UI
3. Ensure that the content doesn't get squished
