Subject: Add custom log handler and expand demo node coverage

Replace default Qt message pattern with a custom handler that matches
open62541 server log format: timestamps with UTC offset, colored
type/category tags padded to 20 chars, and shortened category names.

Add sbyte, byte, datetime, guid, and bytestring node types to all
three demo pages. Add Guid type coercion to writeValue.
