feat: BLE 新增 RS485 地址/波特率读写 + 空闲关蓝牙超时 + 功能码细分

- 新增 CMD_DBN_RW_UART_BAUD (0x31): 读写 RS485 波特率、485 地址、空闲关蓝牙超时
- storage.h: 新增 flash 地址 ADDR_BT_Close_TIMEOUT_Offset(0x10)、Addr_RS485_Baud_Offset(0x11,3B)、Addr_RS485_ID_Offset(0x14)
- 功能码细分: g_function_mode bit0→fm_700bs_disable(0=700BS/1=Modbus), bit1→fm_radar_input_disable(0=光耦/1=复位)
- factory_dev 出厂默认: RS485 ID=1, 波特率=9600, 蓝牙超时=0
- para_store_init 上电从 flash 恢复所有新增配置
