fix(integrations): skip the ledger page when the watchdog announced it

A failure streak reaching the alert threshold paged the operator even
when the watchdog had already announced an open incident for the same
connection. The ledger now checks for that announced incident first,
stamps the streak as announced and sends nothing; the watchdog's
recovery note still ends it.
