🐛(frontend) fix loading comments transaction

[AntoLC]

Purpose

When we load the comments we have to notify the subscribers of the DocsThreadStore. This generates a Yjs transaction that is currently treated as a user-initiated content change that will trigger a patch request when the doc will try to save.
We now update the transaction origin when we notify the subscribers so that we can reliably identify and ignore those transactions in the useSaveDoc hook.

Walkthrough

The PR implements Yjs transaction integration for comment updates to fix loading comments transaction behavior. A new origin constant (COMMENT_UPDATE_ORIGIN) is introduced to mark comment-driven updates. The DocsThreadStore now accepts an optional Y.Doc parameter and wraps subscriber notifications within Yjs transactions when a document is present. The useSaveDoc hook imports this origin constant and filters out comment-originated updates to prevent them from being marked as local changes. Additionally, the useComments dependency array is updated to recompute the threadStore when the document changes.
