启用 BLE 5.0 2M PHY 图传加速 + 移除未使用的 BluFi 组件 + BLE 断连内存泄漏修复
1、dzbj_ble.c 新增 BLE 5.0 2M PHY 请求（连接时自动协商，不支持则回退 1M）；
2、dzbj_ble.c 新增 PHY 更新事件日志（tx_phy/rx_phy: 1=1M, 2=2M, 3=Coded）；
3、dzbj_ble.c 断连时清理未完成的图片传输状态，释放 img_data/filepath/file_img 防止内存泄漏；
4、移除未使用的 BluFi 组件依赖（Kconfig select、编译检查、sdkconfig），解除与 BLE 5.0 的兼容冲突；
5、sdkconfig.defaults 及生产环境配置统一启用 BLE 5.0 + 保留 BLE 4.2 legacy advertising 兼容；
