Adds the CPU / memory / swap / disk dashboard cards to IndexPage,
backed by a useStatus() composable that polls /panel/api/server/status
every 2 s and a Status / CurTotal model ported from the legacy inline
classes in index.html.
- models/status.js — Status & CurTotal classes (CurTotal exposes
reactive .percent and .color computed-style getters; Status maps
the API payload + xray state to color/message strings)
- composables/useStatus.js — 2s polling with shallowRef so each fetch
swaps the whole Status object atomically. WebSocket integration
intentionally deferred — the legacy panel falls back to this same
2s polling when its websocket drops, so we ship the proven path
first and add WS on top in a later sub-phase.
- pages/index/StatusCard.vue — four a-progress dashboard widgets in
a 2x2 grid (mobile collapses to a 1x4). CPU widget exposes a
history button; the modal it opens is part of 5c-iv.
- IndexPage now consumes both, plus useMediaQuery so the layout
responds to viewport changes.
AD-Vue 4 changes: <a-icon type="area-chart"|"history"> dropped in
favor of explicit AreaChartOutlined / HistoryOutlined imports.
<a-tooltip slot="title"> → <template #title>.
i18n strings still hardcoded English (Phase 7 wires up vue-i18n).
