fix(web): v0.2 round-9 workbench: gate diagnostics live aggregation (HWLAB #775 round 6) (#789)

Continues HWLAB #775 round 6 by restoring the gate diagnostics live
aggregation that the React migration left as a placeholder. Uses
the live `/v1/diagnostics/gate` endpoint (which the round-1 api
client already declared) and renders status / filter / search
controls per `app-conv.ts:277-340`.

## 修复对照

| 类别 | 迁移前 (`893f46bc`) | 迁移后 (round 6) | 状态 |
|---|---|---|---|
| **Gate 拉取** | `app-device-pod.ts:1192-1220` `loadGateDiagnostics` 调 `/v1/diagnostics/gate` | `hooks/useGateDiagnostics.ts` `useGateDiagnostics` hook 走 `api.gateDiagnostics()` + `state` 缓存 rows / payload / loadedAt / error | ✅ 对齐 |
| **Gate 过滤** | `app-conv.ts:309-340` `filteredGateRows` 按 status filter + search 7 字段全文搜 | `hooks/useGateDiagnostics.ts:filterGateRows` 同样 filter + 7 字段 join 全文搜 | ✅ 对齐 |
| **Gate 表格渲染** | `app-conv.ts:340-360` `renderGateTable` 8 列硬编码 | `components/gate/GateView.tsx` 8 列 + StateTag + `data-status-key` 标识（pass / blocked 边色） | ✅ 对齐 |
| **Gate tone 评估** | `app-conv.ts:383-386` `gatePayloadTone` | `hooks/useGateDiagnostics.ts:gatePayloadTone` | ✅ 对齐 |
| **占位 fallback** | 迁移后 round-1 仅放占位 | `GateView` `liveBlockerRow` 把 `response.error` 当 blocked 行渲染 | ✅ 对齐 |

## 改动

- 新增 `web/hwlab-cloud-web/src/hooks/useGateDiagnostics.ts`（153 行）
- 新增 `web/hwlab-cloud-web/src/components/gate/GateView.tsx`（88 行）
- `web/hwlab-cloud-web/src/App.tsx` — 删除占位 `GateView`，import 新版
- `web/hwlab-cloud-web/src/components/shared/StateTag.tsx` — `title` 属性
- `web/hwlab-cloud-web/src/styles/workbench.css` — `.gate-raw` / `tbody tr[data-status-key]` 边色

## 验收

- `bun run check` 通过（Vite build + 2/2 dist freshness test pass）
- `bun run scripts/tsc-check.ts` 通过（strict React TSX, 0 explicit any）
- `bun test` 2 pass / 0 fail
- `bun run build` 9 dist files verified fresh；`app.js` 230917 → 234676 bytes；`index.css` 19062 → 19414 bytes
- 所有改动文件 < 400 行前端 guard
