fix(scanner): bound native backlog fixture resources

Keep native scanner backlog restart fixtures within low file descriptor limits by reducing the native-only disk layout, making fixture shutdown drain background work, and avoiding long-lived ECStore retention from background loops.

Convert ECStore-backed background refresh/recovery/monitor tasks to upgrade weak owners only while doing work so completed test stores release their disk graph before the next native fixture starts.
