Commit Message

test(monitoring): fix flaky disk metrics emission test (#1078)

execute_disk_metrics/0's test asserted that drained disk events had
unique mountpoints. But the PromEx OsMon poller runs during tests
(metrics_disabled is false, prom_poll_rate 500ms) and emits the same
[:prom_ex, :plugin, :osmon, :disk] event on its own timer. When a poll
tick lands in the test window, drain_events collects a second round of
mountpoints and the uniqueness assertion fails intermittently.

Assert coverage instead of uniqueness: our explicit call emits one event
per mountpoint (so expected is a subset of received deterministically),
and extra poller rounds only add duplicates the subset check tolerates.

## What kind of change does this PR introduce?

make test less fragile

## What is the current behavior?

test can fail due to race condition

## What is the new behavior?

let it race, don't fail it

## Additional context
