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.

Use the canonical Docker host identity for token bindings after a matched reconnect, preserve previous/current identity aliases for recreated containers, and keep rejecting token reuse by genuinely different Docker hosts.
Record the RC3 release-gate evidence for the Docker-in-LXC reconnect path.
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
Introduces GET /api/connections and POST /api/connections/probe as the
backend half of the one-ledger / one-editor connection redesign.
- GET /api/connections aggregates PVE/PBS/PMG/VMware/TrueNAS/agent rows
into a unified Connection shape with derived state (active, paused,
unauthorized, unreachable, stale, pending) computed from in-memory
scheduler health plus agent Host.LastSeen. No new persisted state.
- POST /api/connections/probe fingerprints a host across the five
supported products in parallel (2s dial + 1s read, 3s total, max 5
concurrent). Admin-gated (RequireAdmin + ScopeSettingsWrite) to block
unauthenticated SSRF against internal hosts.
- Disabled bool on PVEInstance/PBSInstance/PMGInstance (zero-value =
enabled, preserves existing nodes.json); pollers skip disabled
instances at client init, reconnect, and per-node iteration.
- NodeConfigRequest/Response gain Enabled; write path translates
*bool -> Disabled so omitted field leaves state untouched.
- ConnectionsAPI frontend client (list/probe) typed off the Go shape.
Contracts updated: api-contracts, monitoring, agent-lifecycle,
performance-and-scalability, storage-recovery. Proofs added:
contract_test.go JSON snapshot for Connection and ProbeResponse,
monitoring guardrails for the Disabled-skip behavior, and a vitest
mock-client test for ConnectionsAPI.
Frontend editor / drawer / table rewrite lands in a separate block.
Stop treating every fuse.* filesystem as a remote mount in the shared disk filter so local user-space filesystems such as mergerfs remain visible to host disk stats and alerts while explicit remote fuse types like sshfs still stay filtered.
