fix: CRUD Upload Queue Monitoring

[stevensJourney]

Overview

#254 Added monitoring of the ps_crud CRUD upload operations.

The monitoring relies on ps_crud rows being consumed and removed by the BackendConnector uploadData method. An upload delay is added if the CRUD entry at the head of the queue has not been changed between calls to uploadData.

The ps_crud table contains id and data columns. id Should be a unique incrementing integer while the data column contains JSON of the CRUD data change operation.

The raw ps_crud entry is parsed into a CrudEntry instance which exposes the data above. The mapping in the parsing maps ps_crud:id => CrudEntry.clientId and ps_crud:data:id to CrudEntry.id.

The previous implementation incorrectly assumed CrudEntry.id was the ps_crud:id column value. This causes the monitoring check to think CRUD operations have not been consumed if there are multiple ps_crud operations for the same row (with the same data id). This causes a delay in uploads if a single row has been mutated multiple times.

This PR updates the CRUD monitoring to use the correct id value. Unit tests are also added to ensure the delay functions as planned.
