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
