feat(android): 使用 Kavascan BlockScout API 同步交易记录
替换慢速的 eth_getLogs 区块扫描方案为官方推荐的 BlockScout REST API：
- 使用 /api/v2/addresses/{address}/transactions 端点
- 一次性获取所有交易历史（自动分页）
- 支持 ERC-20 代币转账和原生 KAVA 转账
- 从 30-45 秒优化到 < 5 秒
- 解析 token_transfers 字段识别代币类型
- 根据合约地址映射到 GREEN_POINTS/ENERGY_POINTS/FUTURE_POINTS
