bingo: default to the operational card

The card led with construction projects (Sber Balakovo at #1, MOS7,
MOS11, Yandex Vladimir-2), so the first thing visitors saw was not what
actually runs today. Make the operational-only card the bare URL and
move the full list to ?view=all. The variant is noindex with canonical
to the bare page, old ?view=operational links still land on the default,
and the admin dashboard tile follows the public default.
