When sending workspace chat, we can pass an optional session id but when doing fetch workspace chat history, there is no way to filter by session.

Along this line https://github.com/Mintplex-Labs/anything-llm/blob/79ce26de815b6d91ff2db8ce1a59750c4d6290e0/server/models/workspaceChats.js#L69C26-L69C56, the session id was somehow set to null. Maybe we allow filtering by session id if provided? (optional query param)
