Updates tailscale/tailscale#1634
There was a logic issue in the captive detection code we shipped in https://github.com/tailscale/tailscale/pull/12707.
Assume a captive portal has been detected, and the user notified. Upon switching to another Wi-Fi that does *not* have a captive portal, we were issuing a signal to interrupt any pending captive detection attempt. However, we were not also setting the `captive-portal-detected` warnable to healthy. The result was that any "captive portal detected" alert would not be cleared from the UI.
Also fixes a broken log statement value.

Updates tailscale/tailscale#1634
This PR introduces a new `captive-portal-detected` Warnable which is set to an unhealthy state whenever a captive portal is detected on the local network, preventing Tailscale from connecting.
