Add UploadForwardMsgV2 support for multi-message forwarding

Introduces UploadForwardMsgV2 transformer and integrates it into the message sending flow to support forwarding multiple messages with custom action commands. Updates related interfaces and logic to handle UUIDs and nested forwarded messages, improving flexibility and extensibility for message forwarding operations.
