0.20.4

Bugfix. This is a patch to 0.20.3 to fix the WiFi bridge sensor.

Fixed

The Bridge: WiFi sensor now appears on a normal boot. In 0.20.3 the Wi-Fi feature checked for router trackers once during startup, before most router integrations would have time to load and report. On a normal system that check finds nothing, the sensor is not created, and Wi-Fi outage detection stayed off even though the trackers were there. Now, detection retries until the router is fully loaded, and the sensor appears when the device trackers are detected. Systems without router trackers are unaffected and the WiFi bridge is not created.

The diagnostics download now includes a Wi-Fi section: how many devices are matched to a tracker, which tracker each is matched to, and whether an outage is in progress. This is the information that would have made the 0.20.3 fault visible from a download instead of a support conversation.
