Status summary should consider loss differently if the current loss is 100%

In this case, dgt-dzd-fra-fr5:dgt-dzd-mrs-mrs1 should be considered "down". The 79.4% loss for 2h is less relevant than 100% loss for the last 5 minutes.

Proposed solution: Status summary uses loss over last 24h, unless the most recent 5 minutes are 100% loss.

As a further example of the 24h loss being a poor representation of current state: In the posted example, the was-chi link is also probably actually completely down at the time.
