Implement 9/10 check strategy:
- 9 out of 10 connectivity checks go to 1.1.1.1 (Cloudflare DNS)
- 1 out of 10 checks go to Qobuz to verify service availability
This prevents false offline detections when the app is making many
concurrent API calls (e.g., loading genre hierarchies), which could
trigger Qobuz rate limiting and cause timeout-based false positives.
Also reduced timeout from 15s to 10s and retry wait from 2s to 1s
since 1.1.1.1 responds much faster than Qobuz.
