Test: verify health check scheduler records container state

[GeiserX]

Context

CashPilot runs a health check scheduler every 5 minutes that records container state in the health_events table. The health score (0-100) is calculated from uptime and restart frequency.

Task

1. Write a test that simulates health events (start, check_ok, check_down, restart)
2. Verify the health score calculation produces expected values
3. Verify the /api/health/scores endpoint returns scores in the correct format
