The word "breached" in infrastructure monitoring was confusing users
as it implied a security breach. Renamed to "exceeded" which better
describes threshold violations (e.g. "threshold exceeded").
## Changes
- Renamed monitor status value from "breached" to "exceeded" across
server types, status service, queue helper, notification builder,
email subject lines, and MongoDB aggregation queries
- Renamed client types, status box/label components, translation key,
and infrastructure page props to match
- Added DB migration (0005) to update existing monitors with the old
status value
