feat(02-06): cache Home's system/update/storage groups and guarantee wallet freshness on re-entry

- System stats (homeStatus.refresh), update status and cloud storage usage
  are now every-entry, TTL-gated useCachedResource entries (10s/300s/30s),
  hosted in Home.vue rather than inside the homeStatus Pinia store — a
  store's own defineStore(id, setup) runs in a bare effectScope where
  onActivated() silently no-ops (same finding as 02-05's Mesh.vue)
- Wallet is the deliberate exception (T-02-13): a new home.wallet-status
  resource wraps the existing loadWeb5Status() composite fetch and
  revalidates UNCONDITIONALLY on every activation rather than TTL-gated,
  keeps the prior figure rendered throughout, and persist:false (never
  written to sessionStorage). hydrateWalletSnapshot()'s separate localStorage
  path is untouched.
- Read Web5.vue's two existing resources (web5.networking-profits,
  web5.lnd-info) and did NOT share either key: profits is an unrelated
  dataset, and lnd-info's own default persist:true (Web5.vue out of this
  plan's file scope) would leak balance data via its own independent
  refresh cycle regardless of what Home declares, and Home's wallet fetch
  is a strictly broader 7-call composite (not the same single-call dataset)
- dedup:true added to all 12 underlying rpcClient calls (Home.vue's wallet
  composite + checkUpdateStatus, homeStatus.ts's 5 status calls)
- RefreshIndicator wired next to the Home header, bound to the wallet
  resource's loadState
- The websocket wallet-push path and hydrateWalletSnapshot's pre-network
  paint are both left exactly as 02-04 placed them
