Automatic Greeting Feature

[milesha]

Motivation

We aim for the AI mentor to directly engage with the student at the beginning of each session (aka send the first message) to clarify its purpose and enhance the flow of interaction.

Description

• A separate file including the persona_prompt - an overarching description of the Mentor behaviour.
• An extra node in the LangGraph responsible for the greeting of the user is the received message is empty.
• Skeleton for the messages is added as well as "isLoading" state

Testing Instructions

• Loading State of the message view can be found in Storybook under app/mentor/messages/isLoading
• Start the webapp, intelligence-service and application-server. Important: your user should have "mentor_access" role.
• Open the mentor interface and click the "New Session" button -> afterwards, you should automatically get the first message from the AI mentor

Very nice PR!

Added a few smaller remarks and one larger suggestion for a redesign of a prompt management solution. If you prefer to solve it in a separate PR, just stack it on top of this one.

I am probably missing something here since this isn't new code - but the messageContent is currently not passed to the IS, right?

[milesha]

@GODrums the idea is that the latest message is first saved to the session and then passed as part of the message history to the intelligence-service, we do not send it separately.

[GODrums]

That makes sense.
Since messageContent is not used in generateResponse directly, we can just omit it as parameter then?

[milesha]

@GODrums you are totally right - thanks for noticing! :)

Looks good to me, thanks for implementing the suggestions!

Tested it locally.

I'll merge and deploy it together with the Docs-PR later today.
