Anso 71678081f0 refactor(frontend): extract useFleetUpdateStatus + useFleetPolling from FleetView (F5-7) (#921)
Move the update workflow state machine and the polling driver out of the
FleetView shell into two dedicated hooks under FleetView/hooks/. No
behavior change.

useFleetUpdateStatus owns updateStatuses + updatingNodeId + the four
modal/dialog/reconnecting state slots, the synchronously-held
updateStatusesRef, and every callback that touches the update workflow
(fetchUpdateStatus, triggerNodeUpdate, confirmLocalUpdate,
triggerUpdateAll, dismissNodeUpdate, retryNodeUpdate). The inline four-
line "Check Updates" handler collapses into a single checkUpdates()
callback returned from the hook.

useFleetPolling is a pure side-effect hook that owns the initial-mount
fetch, the paid-tier 30s overview + 120s update-status interval pair,
and the 5s fast-poll accelerator gated on hasUpdatingRef. The polling
hook does not know about update semantics; the consumer passes in
updateStatuses and the fetch callbacks.

Shell drops from 523 to 385 LOC. useState calls drop from 13 to 6,
useEffect from 4 to 0, useCallback from 8 to 2, useRef from 2 to 0.

Tested manually in browser: fleet view loads, masthead populates, Check
Updates opens the sheet and fetches statuses, Refresh fires
fetch-overview, no console errors from the refactor (existing
unreachable-remote-node WebSocket failures are unrelated). Dev servers
killed after validation.
