fix: Avoid creating duplicate note blocks in Notion

[dvanoni]

Problem

As reported in #463, duplicate "Zotero Notes" blocks end up created when note content fails to sync. This occurred because block IDs were not saved into Zotero when a note failed to sync—even though the container blocks (i.e. "Zotero Notes" and the note heading) were indeed created in Notion. Without saving the block IDs into Zotero, the next sync attempt had nothing to reference and thus created additional container blocks.

Solution

We now save block IDs before attempting to sync the note content so that, if the note content fails to sync, we've already saved references to the block IDs to be used for the next sync attempt. Additionally, if we successfully create the "Zotero Notes" container but fail to create the note heading container, we still save the block ID of the "Zotero Notes" container.
