refactor(core): implement doc created/updated by service (#12150)

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit

- **New Features**
  - Documents now automatically track and display "created by" and "updated by" user information.
  - Document creation and update timestamps are now managed and shown more accurately.
  - Workspace and document metadata (name, avatar) updates are more responsive and reliable.
  - Document creation supports middleware for customizing properties and behavior.

- **Improvements**
  - Simplified and unified event handling for document list updates, reducing redundant event subscriptions.
  - Enhanced integration of editor and theme settings into the document creation process.
  - Explicit Yjs document initialization for improved workspace stability and reliability.
  - Consolidated journal-related metadata display in document icons and titles for clarity.

- **Bug Fixes**
  - Fixed inconsistencies in how workspace and document names are set and updated.
  - Improved accuracy of "last updated" indicators by handling timestamps automatically.

- **Refactor**
  - Removed deprecated event subjects and direct metadata manipulation in favor of more robust, reactive patterns.
  - Streamlined document creation logic across various features (quick search, journal, recording, etc.).
  - Simplified user avatar display components and removed cloud metadata dependencies.
  - Removed legacy editor setting and theme service dependencies from multiple modules.

- **Chores**
  - Updated internal APIs and interfaces to support new metadata and event handling mechanisms.
  - Cleaned up unused code and dependencies related to editor settings and theme services.
  - Skipped flaky end-to-end test to improve test suite stability.
