feat: updated org model and sync registries to prevent locking organi…

[wwills2]

this PR removes the organization model mutex aquisition intoduced in #1224. the sync-registries task a still acquires the mutex prior to inserting data into the audit table as part of a SQLite transaction, and the audit model checks the mutex before reads.

The update query to update the organization records with the latest registry hash has been moved outside of the audit update SQL transaction to prevent locking the organization table for the duration of the audit sync. Additional validation and correction logic has been added to address the newly decoupled nature of the audit and organization updates (they still happen synchronously relative to eachother, but they are now not part of the same transaction).

when the sync registries task runs, it checks to make sure the organization registry hash matches the latest audit record hash, and corrects the record on discrepancies.
