feat(ch390): optimize SPI transfer, MAC fallback, and build settings for V1.0.0

- increase UART DMA/ring buffer sizes for mux traffic - switch SPI1 to Mode0 with prescaler /2 and align CubeMX settings - refactor CH390 memory read/write path with chunked SPI read and HAL bulk write - fallback to hardware MAC when configured MAC is invalid (all-zero) - add mux frame RTT logs and remove redundant UART1 polling - update Keil post-build viewer integration and include build viewer artifacts - update AT manual with all-zero MAC behavior

+**MAC 设置说明：**
+
+当MAC设置为全0时，固件将使用硬件MAC地址，此时通过AT+?查询到的MAC地址即为当前生效的硬件MAC地址。
