fix(esp8266): correct UART port assignment for serial initialization

ESP8266 only supports UART1 as TX-only. Previously, the code attempted to use UART1 as RX and UART0 as TX, causing initialization failure. This commit swaps the UART ports, assigning UART1 as TX and UART0 as RX, resolving the issue. fix #83 and #92
