Previously, when accepting service discovery changes — e.g. clicking Accept all or removing vanished services — those services could immediately reappear as new (undecided) in the service discovery view.

This happened because the discovery view was refreshed by re-running a discovery preview using cached agent data. Since the services had just been removed from the autochecks, the cached data caused them to be re-discovered as new services.

The service discovery view now correctly reflects the applied changes without re-running the discovery preview.
