Verify a Sentry suppression filter is alive by checking for the tag it sets, not by reading it

A Sentry beforeSend filter keyed on mechanism.type === 'sveltekit' never fires: @sentry/sveltekit emits auto.function.sveltekit.handle_error. Any suppression filter that also sets a tag can be proven alive or dead in one query -- sample 100 events and check whether the tag it sets is present.
