feat(exchange): add Bybit Futures support (#1100)

* feat(exchange): add Bybit Futures support

- Add Bybit Go SDK dependency (github.com/bybit-exchange/bybit.go.api)
- Create trader/bybit_trader.go implementing Trader interface for USDT perpetual futures
- Update config/database.go to include Bybit in default exchanges
- Update manager/trader_manager.go to handle Bybit API key configuration
- Update trader/auto_trader.go to add BybitAPIKey/BybitSecretKey fields and bybit case
- Add Bybit icon to frontend ExchangeIcons.tsx

Bybit uses standard API Key/Secret Key authentication (similar to Binance).
Only USDT perpetual futures (category=linear) are supported.

* test(bybit): add comprehensive unit tests for Bybit trader

- Add BybitTraderTestSuite following existing test patterns
- Interface compliance test (Trader interface)
- Symbol format validation tests
- FormatQuantity tests with 3-decimal precision
- API response parsing tests (success, error, permission denied)
- Position side conversion tests (Buy->long, Sell->short)
- Cache duration verification test
- Mock server integration tests for API endpoints

All 12 Bybit tests pass.

* fix(frontend): add Bybit support to exchange config forms

修復前端對 Bybit 交易所的支持：
- 添加 Bybit 到 API Key/Secret Key 輸入欄位顯示邏輯
- 添加 Bybit 的表單驗證邏輯
- 修復 ExchangeConfigModal.tsx 和 AITradersPage.tsx
