Problem:

System Health currently sends email notifications only for "Confirmed Impact" incidents (AutoHOTs with tenant-level attribution). Incidents classified as "Advisory" appear only in the UI — no email is sent, even when customers are objectively impacted. Admins have no way to opt in to these notifications.

Why it matters:

• Advisory incidents include login, identity, and SCIM issues that have no CMON coverage and can never become Confirmed Impact under the current model

• Admins who rely on email as their alerting channel miss real incidents

• Erodes trust in System Health as the recommended notification mechanism

Proposed Solution:

Add a notification preference toggle for org admins:

• Default: Notify for Confirmed Impact only (current behaviour)

• Opt-in: Notify for all incidents including Advisories
