Bug: Redis cache health check fails with 'Redis set/get test failed'

[lbedner]

Bug Description

Redis cache shows as unhealthy in Overseer with the error message:

Cache health check failed: Redis set/get test failed

Also, Illiana doesn't actually have up to date information about Redis, as she is currently saying it's healthy.

Steps to Reproduce

1. Start the application with Redis component enabled
2. Open Overseer dashboard
3. Observe Redis card showing unhealthy status

Expected Behavior

Redis cache health check should pass when Redis is running and accessible.

Current Behavior

Health check fails with "Redis set/get test failed" message.

Investigation Needed

• Check Redis connection configuration
• Verify the health check implementation in Redis component
• Check if Redis is actually running and accessible
• Review the set/get test logic in the health check
