## Summary by CodeRabbit
* **New Features**
* Optional block properties are now supported (e.g., flat-table), with
default values applied automatically when not set.
* **Bug Fixes**
* More reliable initialization and syncing of block properties, ensuring
defaults appear consistently.
* Change notifications now correctly reflect updates to
optional/defaulted properties.
* **Tests**
* Added tests verifying optional property behavior, default application,
syncing, and change events.

Splice will produce large yjs updates for splice because it will call insert and delete operation for every item in yarray.

## Summary by CodeRabbit
- **New Features**
- Added support for `splice`, `shift`, and `unshift` methods on reactive arrays, enabling enhanced dynamic array operations with synchronization.
- **Tests**
- Expanded test coverage for array operations including `push`, `splice`, `shift`, and `unshift`, verifying complete array state after each change.

## 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.

The primary purpose of this PR appears to be:
1. Simplifying the change notification API by removing the redundant value parameter from callbacks
2. Improving the reactive system's handling of specialized types (Text and Boxed) in flat data
3. Adding better test coverage for text handling in the flat data model
The new code should be more efficient as it:
- Avoids unnecessary iterations when objects aren't empty
- Has clearer path management
- Reduces redundant object traversals
