Retire runtime/API/UI monitored-system volume enforcement now that infrastructure monitoring is no longer capped.
Keep only legacy metadata scrubbing and purchase-start compatibility for old max_monitored_systems references.
Rename the remaining preview surface to monitored-system impact and make previews explanatory rather than save-blocking.
Update subsystem contracts and RA7 evidence for the caps-retired invariant.
Treat OIDC, SAML, and multi-provider SSO as included Community capabilities while retaining advanced_sso as a compatibility key. Remove SAML-specific paywalls and paid-upgrade copy from runtime, settings UI, entitlement snapshots, docs, journey proof, and subsystem contracts.
Refs #1449
Parse the /proc/mdstat operation keyword for mdadm arrays and propagate it through host reports, models, unified resources, monitoring views, alert metadata, and AI storage summaries.
Treat recovery and reshape as rebuild signals while silencing routine check and resync maintenance, with fallback rebuild detection only when no mdstat operation is available.
Tests cover mdstat operation parsing plus recovery, check, and resync alert behavior.
Fixes#1446
Remove local upgrade-metrics API registration, settings payload wiring, startup store migration, and backend conversion recorder hooks from the normal product runtime.
Delete the retired conversion/funnel and metering packages from compiled licensing code, and extend diagnostics boundary audits and governance contracts so maintainer commercial analytics cannot return through Settings or diagnostics.
