The recent updates ensure that documents are detached when a client is deactivated. This includes new error handling, added functionality in database methods, and enhanced testing scenarios to validate the changes. The Deactivate function now comprehensively handles document detachment, client info updates, and proper deactivation across various components of the server, ensuring robustness and consistency.

What this PR does / why we need it?
This PR addresses the issue where documents attached to a client are not being properly detached during deactivation. Specifically, information about document detachment is not being reflected in the database, leading to situations where documents remain attached to a deactivated client.
By implementing this fix, attempting to delete a document from the dashboard will now correctly handle the scenario where the document is attached, resolving the problem outlined in issue #758.

Special notes for your reviewer:
The DB resources below should be updated when executing Client.Deactivate:
Updating ClientInfo involves updating a single MongoDB document, ensuring ACID compliance. However, as SyncedSeq is spread across multiple documents, ACID compliance cannot be guaranteed.
In addition, I have considered the order of updates for ClientInfo and syncedSeq, along with the potential issues or advantages that may arise.
A. ClientInfo -> SyncedSeq
B. SyncedSeq -> ClientInfo
In conclusion, for this PR, we have decided to update in the order of
A. ClientInfo -> SyncedSeq. We plan to add correction logic later to handle cases where the ClientInfo update succeeds but the SyncedSeq update fails.Does this PR introduce a user-facing change?:
