sns: fix internal flow

- magnitudes vector grows by calling copy ctor, ensure filter never gets deleted
- ensure we can't use magnitude member instead of ctor arg
- more magnitude references instead of using index access
- additional checks for isnan, fix report never triggering
- drop event callback. at least for EventSensor, we already have
  report with min / max value change triggers
