New integration notification-monitoring endpoints added: GET /v2/integrations/{integrationId}/notifications/history (paginated history of fired and suppressed notifications), GET /v2/integrations/{integrationId}/notifications/status (live per-rule alert state and baseline bands), and POST /v2/integrations/{integrationId}/notifications/test (send a test notification to the calling user)
Integration settings now carry an optional notifications configuration object (recipients, delivery channels, alert rules, and digest schedule) on the v1 and v2 create, update, and read endpoints
