## Summary by CodeRabbit

* **Bug Fixes**
* Improved document filtering to exclude settings documents and empty
blobs from embedding and status calculations.
* Enhanced embedding jobs to skip processing deprecated documents if a
newer version exists, ensuring only up-to-date documents are embedded.
* **New Features**
* Added a mutation to trigger the cron job for generating missing
titles.
* **Tests**
* Added test to verify exclusion of documents with empty content from
embedding.
* Updated embedding-related tests to toggle embedding state during
attachment upload under simulated network conditions.
