[BUG FIX] Exception handling and enabling graceful shutdown of connection

[IronJam11]

PR Description:

Closes #1350

Deliverables:

• Adds logging for errors encountered in the handle() function.
• Ensures graceful shutdown of the connection in the event of an error.

Changes:

• Error Handling in handle():

  • Added a try-except block to catch exceptions during the handle() function execution.
  • Logs the error with a detailed traceback using logger.error().
  • Sends a 500 Internal Server Error response using self.send_response() when an error occurs.

  except Exception:
      logger.error(f"Error in handle(): {traceback.format_exc()}")
      await self.send_response(500, b"Internal Server Error")
      raise

• Graceful Shutdown:

  • Ensured that after sending the error response, the connection is gracefully terminated using self.send_response().

• Improved Error Handling in http_disconnect():

  • Added robust error handling during the disconnect phase to ensure proper cleanup and termination of the connection.
