feat(ui): 依据参考图全面重构资产展示 UI，实现纯净的原生币种数据面板

 - 升級了 Dashboard 資產卡片 UI，新增累計分紅展示，並優化了成本數據的格式化判斷邏輯。
 - 修復了 `avgCostFormatted` 的判空邏輯，將 `Big.eq(0)` 修正為 `Big.eq('0')`，確保當 `pos.avgCost` 存在且不為 0 時能正確格式化，不再顯示 `¥-`。
 - 在資產卡片中新增「累計分紅」行，展示 `accumulatedDividendsCny` 數據，保持與其它 CNY 數據一致的 `opacity-50` 樣式。

+## 持倉引擎 Native 幣種算法重構 (Task 38)
+- 重構底層盈虧引擎，全面轉向 Native 原生幣種計算，新增浮動/累計盈虧及百分比指標。
+- 徹底分離 Native 與 CNY 計算：單隻股票的成本與盈虧全部改用 Native (原幣種) 進行計算。
+- 新增 Native 成本指標：`totalBuyCostNative` (總買入成本)、`realizedPnlNative` (已實現盈虧)、`accumulatedDividendsNative` (累計分紅)。
+- 新增 Native 成本均價：`avgCostNative = totalBuyCostNative / totalBuyQuantity`、`dilutedCostNative = (totalBuyCostNative - realizedPnlNative - accumulatedDividendsNative) / currentQuantity`。
+- 新增浮動盈虧指標：`marketValueNative = latestPrice * currentQuantity`、`floatingPnlNative = marketValueNative - (avgCostNative * currentQuantity)`、`floatingPnlPercent = floatingPnlNative / (avgCostNative * currentQuantity) * 100`。
+- 新增累計盈虧指標：`cumulativePnlNative = floatingPnlNative + realizedPnlNative + accumulatedDividendsNative`、`cumulativePnlPercent = cumulativePnlNative / totalBuyCostNative * 100`。
+- SELL 交易的已實現盈虧計算從 CNY 基準改為 Native 基準，CNY 計算保留用於前端兼容展示。
+
+## 全面重構資產展示 UI (Task 39)
+- UI 全面升級，復刻專業券商級數據排版，合併攤薄/成本，引入原生幣種盈虧百分比展示。
+- 徹底清理所有帶 (CNY) 和 (USD) 混雜的舊布局，所有 Native 金額根據 `baseCurrency` 渲染正確貨幣符號（USD→$、CNY/HKD→HK$、JPY→¥）。
+- 資產卡片全新字段：現價、市值、持倉、攤薄/成本（合併為 `[dilutedCostNative] / [avgCostNative]` 格式）、浮動盈虧（帶百分比）、累計盈虧（帶百分比）、持倉天數。
+- 盈虧顏色遵循中國市場慣例：大於 0 顯示紅色，小於 0 顯示綠色。
+- 所有百分比保留 2 位小數，0 值正常顯示 `0.00`。
+- 卡片佈局優化為響應式 `grid-cols-1 md:grid-cols-2 lg:grid-cols-3`。
