Improve UI for persisting bridge scanned from QR code
As reported on #19281 (comment 200112), the cheapest possible implementation of Allow persisting bridge scanned from QR code (#19281 - closed) is not ideal.
The whole persistence UI on the "Configure a Tor bridge" screen is visually bound to the "Enter a bridge that you already know" section:
So even if the switch is technically sensitive, which conveys the message that it's OK that I interact with it, I think it's too subtle a hint for a user who has scanned a QR code.
