High-level PR Summary

This PR delivers a comprehensive revamp of the Documents UI with Notion-style design patterns and mobile responsiveness, implements real-time document synchronization using Electric-SQL with PGlite, fixes duplicate notification key errors in the inbox, and adds loading skeletons for private and shared chats. The Documents UI now features a cleaner table layout with enhanced filters, improved pagination, user attribution (created_by_name), and better mobile support. The Electric-SQL integration includes critical bug fixes for duplicate key errors caused by unstable cutoff dates and adds an onMustRefetch handler to prevent data conflicts during shape invalidation.
