Mapload anomalies are no longer orbit points-of-interest (#81431)

## About The Pull Request

Mapped-in anomalies no longer register as points-of-interest in the
orbit menu. This is primarily for the hollow anomalies from the anomaly
research ruin. Player-stabilized anomalies, and regular event anomalies,
will still show up here.
## Why It's Good For The Game

These damn things take up over half the misc tab. Less clutter in the
orbit menu.
