✨(frontend) warn users when the connection falls back to TURN

Highlight in the connection test when the user is connecting
through a TURN relay, especially over TLS or TCP. This usually
indicates that some network configuration is required on their
side, and gives them a concrete signal to pass to their IT team.

Suggested by a technical user, this is a first step toward making
users more autonomous when troubleshooting access to the tool.

Follow-up: show a similar warning in-product when we detect a
mid-meeting fallback to TURN/TLS. A one-time hint for first-time
users would likely be enough.
