Read QC results from SQLite database

In terms of cloud sync, this is conditional on a run being active or completed:

• For a completed run, the local database should be downloaded in its entirety and QC results should be read from the sample_qc_results table.
• For an active run, the local database should be ignored and QC results should be read from a single CSV file that is updated with each sample acquired.
