[MIRROR] Fixes ore vent descriptions stacking, fixes potential exploi…

…ts with ore vent scanning (#690)

* Fixes ore vent descriptions stacking, fixes potential exploits with ore vent scanning (#81174)

## About The Pull Request

- Scanning ore vents did a do_after to do the actual scan, but if the
do_after failed, it didn't cancel the scan proc, and rewarded you points
anyways. So you could just keep cancelling the scan for free points?

- Also there was nothing preventing someone from stacking scans on the
same vent

- Also, when generating the ore description, always override existing
descriptions. Given `generate_description` can be called multiple times,
prevents it from stacking on itself.

## Changelog

:cl: Melbert
fix: Fixed ore vent descriptions looking weird sometimes
fix: Fixed being able to scan an ore vent multiple times at once
fix: Fixed gaining scan points from scannning an ore vent without
finishing the scan
