fix(database): handle connection timeouts gracefully
Previously, connection timeouts would cause the entire request to fail
without retry. This change implements exponential backoff with up to
3 retries before failing.
The timeout threshold has been increased from 5s to 10s based on p99
latency analysis.
Fixes #456
