Fill in new URI credential edit web UI interfaces
- Ref T7221. Our handling of the "git://" protocol is currently incorrect. This protocol is not authenticated, but is considered an SSH protocol. In the new UI, it is considered an anonymous/unauthenticated protocol instead.
- Ref T10241. This fixes the PassphraseCredentialControl so it doesn't silently edit the value if the current value is not visible to you and/or not valid.
Performed a whole lot of credential edits, removals, and adjustments. I'll give this additional vetting before cutting over to it.
