Read a silent in-guest agent's guest drawer readings as last known

A Pulse agent linked into a VM keeps its last report on the VM resource
after it stops reporting: the registry copies the agent's whole facet,
agent.stale included, onto the guest. The guest drawer never read that
flag, so a quiet agent's RAID kept its live colours and "Rebuild: 42% ·
118M/sec", its network rows and version read as current, and nothing
said the agent had gone.

- useWorkloads maps agent.stale onto the row as agentStale, and sets
  disksFromAgent when Proxmox reported no guest filesystems and the
  agent's own disks filled in.
- The guest drawer passes the stopped-reporting reason to RaidCard, puts
  a status line over muted network rows, marks the Pulse Agent row as
  stopped reporting, and reads agent-supplied filesystem rows as last
  known.
- Agent-supplied filesystem rows follow the agent's freshness instead of
  the Proxmox guest-read reason. A VM with a live linked agent but no
  qemu-guest-agent showed the agent's filesystems as "Usage unavailable"
  with advice to install qemu-guest-agent. A stopped VM keeps the Proxmox
  reason, and Proxmox's own guest filesystems keep their read state.

The workload table's disk cell, the drawer History, and the agent's OS,
addresses and physical disk health still carry no stale cue.

 not local table CSS or a duplicate renderer; non-filesystem rows keep the compact
 default. Verification covers the opt-in at this composition boundary and actual
 long-path wrapping in the shared renderer's browser proof.
+A guest's linked Pulse Agent can stop reporting while Proxmox keeps polling the
+VM. `useWorkloads` copies `resource.agent.stale` onto the row as `agentStale`,
+and sets `disksFromAgent` when Proxmox reported no guest filesystems and the
+agent's own `disks` filled in. When that agent is stale, `GuestDrawerOverview.tsx`
+reads the Guest RAID card as last known through the shared `RaidCard`
+`lastKnownReason` prop with `HOST_AGENT_STOPPED_REPORTING_REASON`, puts a status
+line over muted Network rows, reads agent-supplied Filesystems rows through the
+existing `last-known` disk read state, and marks the Pulse Agent row as stopped
+reporting. Agent-supplied filesystem rows follow the agent's freshness rather
+than the Proxmox `diskStatusReason`, which describes Proxmox's own guest reads,
+so a live agent's rows keep their usage and bars. Those rows read as
+unavailable once the guest is stopped, whether its status or the Proxmox
+`vm-stopped` reason says so, and Proxmox's own guest filesystems keep their
+Proxmox read state. The two flags ride the existing row mapping and
+add no query or poll; `GuestDrawer.test.tsx` and `useWorkloads.test.ts` pin
+both sources. The workload table's disk cell and the drawer History still read
+the aggregate disk metric and the Proxmox reason, and the agent's OS, addresses
+and physical disk health carry no stale cue yet.
 Guest, node, and Docker-host drawer headers follow the same frontend-primitives dependency
 boundary for collapse: Workloads owns which inline row is selected and the
 close handler, while
