feat(tss): 添加积分股(eUSDT)和积分值(fUSDT)代币支持

新增功能:
- 添加 ENERGY_POINTS (积分股/eUSDT) 和 FUTURE_POINTS (积分值/fUSDT) 代币类型
- 实现所有 ERC-20 代币的通用余额查询功能
- 支持四种代币的转账功能 (KAVA, dUSDT, eUSDT, fUSDT)
- 更新 UI 显示所有代币余额和代币选择器

代币合约地址 (Kava EVM):
- dUSDT (绿积分): 0xA9F3A35dBa8699c8E681D8db03F0c1A8CEB9D7c3
- eUSDT (积分股): 0x7C3275D808eFbAE90C06C7E3A9AfDdcAa8563931
- fUSDT (积分值): 0x14dc4f7d3E4197438d058C3D156dd9826A161134

技术改进:
- 添加 TokenConfig 工具类统一管理代币配置
- 添加 ERC20Selectors 常量类定义合约方法选择器
- 添加 transaction_records 表用于存储转账历史 (数据库版本升级到 v4)
- 重构余额查询和转账逻辑支持多代币类型
- 所有 ERC-20 代币使用 6 位小数精度

受影响文件:
- Android: Models.kt, TssRepository.kt, TransactionUtils.kt, Database.kt,
          AppModule.kt, TransferScreen.kt, WalletsScreen.kt
- Electron: transaction.ts, Home.tsx
