Test plan

• Both variants scored on every challenge (no synthetic data)
• competition_scores matches CompetitionScoresPayload shape (12 matches, baseline_ran=true)
• DB nuke + reboot loads correctly (25 genomes, 12 variants, 12 vevos, 24 challenges)
• learning_log has 4 entries (created, finalized, integration_report, competition_scores)
