feat(lighter): 完整集成 LIGHTER DEX - SDK + 前端配置 UI (#1085)

* feat(trader): add LIGHTER DEX integration (initial implementation)
Add pure Go implementation of LIGHTER DEX trader following NOFX architecture
Features:
- ✅ Account management with Ethereum wallet authentication
- ✅ Order operations: market/limit orders, cancel, query
- ✅ Position & balance queries
- ✅ Zero-fee trading support (Standard accounts)
- ✅ Up to 50x leverage for BTC/ETH
Implementation:
- Pure Go (no CGO dependencies) for easy deployment
- Based on hyperliquid_trader.go architecture
- Uses Ethereum ECDSA signatures (like Hyperliquid)
- API base URL: https://mainnet.zklighter.elliot.ai
Files:
- lighter_trader.go: Core trader structure & auth
- lighter_orders.go: Order management (create/cancel/query)
- lighter_account.go: Balance & position queries
Status: ⚠️ Partial implementation
- ✅ Core structure complete
- ⏸️ Auth token generation needs implementation
- ⏸️ Transaction signing logic needs completion
- ⏸️ Config integration pending
Next steps:
1. Complete auth token generation
2. Add to config/exchange registry
3. Add frontend UI support
4. Create test suite

* feat: Add LIGHTER DEX integration (快速整合階段)
## 🚀 新增功能
- ✅ 添加 LIGHTER DEX 作為第四個支持的交易所 (Binance, Hyperliquid, Aster, LIGHTER)
- ✅ 完整的數據庫配置支持（ExchangeConfig 新增 LighterWalletAddr, LighterPrivateKey 字段）
- ✅ 交易所註冊與初始化（initDefaultData 註冊 "lighter"）
- ✅ TraderManager 集成（配置傳遞邏輯完成）
- ✅ AutoTrader 支持（NewAutoTrader 添加 "lighter" case）
## 📝 實現細節
### 後端整合
1. **數據庫層** (config/database.go):
   - ExchangeConfig 添加 LIGHTER 字段
   - 創建表時添加 lighter_wallet_addr, lighter_private_key 欄位
   - ALTER TABLE 語句用於向後兼容
   - UpdateExchange/CreateExchange/GetExchanges 支持 LIGHTER
   - migrateExchangesTable 支持 LIGHTER 字段
2. **API 層** (api/server.go, api/utils.go):
   - UpdateExchangeConfigRequest 添加 LIGHTER 字段
   - SanitizeExchangeConfigForLog 添加脫敏處理
3. **Trader 層** (trader/):
   - lighter_trader.go: 核心結構、認證、初始化
   - lighter_account.go: 餘額、持倉、市場價格查詢
   - lighter_orders.go: 訂單管理（創建、取消、查詢）
   - lighter_trading.go: 交易功能實現（開多/空、平倉、止損/盈）
   - 實現完整 Trader interface (13個方法)
4. **Manager 層** (manager/trader_manager.go):
   - addTraderFromDB 添加 LIGHTER 配置設置
   - AutoTraderConfig 添加 LIGHTER 字段
### 實現的功能（快速整合階段）
✅ 基礎交易功能 (OpenLong, OpenShort, CloseLong, CloseShort)
✅ 餘額查詢 (GetBalance, GetAccountBalance)
✅ 持倉查詢 (GetPositions, GetPosition)
✅ 訂單管理 (CreateOrder, CancelOrder, CancelAllOrders)
✅ 止損/止盈 (SetStopLoss, SetTakeProfit, CancelStopLossOrders)
✅ 市場數據 (GetMarketPrice)
✅ 格式化工具 (FormatQuantity)
## ⚠️ TODO（完整實現階段）
- [ ] 完整認證令牌生成邏輯 (refreshAuthToken)
- [ ] 完整交易簽名邏輯（參考 Python SDK）
- [ ] 從 API 獲取幣種精度
- [ ] 區分止損/止盈訂單類型
- [ ] 前端 UI 支持
- [ ] 完整測試套件

* feat(lighter): 實現完整 HTTP 調用與動態市場映射
### 實現的功能
#### 1. submitOrder() - 真實訂單提交
- 使用 POST /api/v1/sendTx 提交已簽名訂單
- tx_type: 14 (CREATE_ORDER)
- 價格保護機制 (price_protection)
- 完整錯誤處理與響應解析
#### 2. GetActiveOrders() - 查詢活躍訂單
- GET /api/v1/accountActiveOrders
- 使用認證令牌 (Authorization header)
- 支持按市場索引過濾
#### 3. CancelOrder() - 真實取消訂單
- 使用 SDK 簽名 CancelOrderTxReq
- POST /api/v1/sendTx with tx_type: 15 (CANCEL_ORDER)
- 自動 nonce 管理
#### 4. getMarketIndex() - 動態市場映射
- 從 GET /api/v1/orderBooks 獲取市場列表
- 內存緩存 (marketIndexMap) 提高性能
- 回退到硬編碼映射（API 失敗時）
- 線程安全 (sync.RWMutex)
### 技術實現
**數據結構**:
- SendTxRequest/SendTxResponse - sendTx 請求響應
- MarketInfo - 市場信息緩存
**並發安全**:
- marketMutex - 保護市場索引緩存
- 讀寫鎖優化性能
**錯誤處理**:
- API 失敗回退機制
- 詳細日誌記錄
- HTTP 狀態碼驗證
### 測試
✅ 編譯通過 (CGO_ENABLED=1)
✅ 所有 Trader 接口方法實現完整
✅ HTTP 調用格式符合 LIGHTER API 規範
