Add USART2 support and modify system clock configuration

Browse Source 
- Implemented USART2 initialization and interrupt handling.
- Added a function to send data to the server via USART2.
- Updated the main application to utilize USART2 for communication.
- Changed system clock configuration to use HSE and PLL for higher frequency.
- Adjusted SPI1 baud rate prescaler for improved performance.
- Enhanced LED control logic based on RFID card detection.
- Updated project configuration to reflect new USART2 settings.
