fix: detect unresolved secrets in SqlDataSource

Add resolveCredential method to SqlDataSource that detects unresolved
workspace secrets patterns like 'secrets.ATHENA_USER' and '[secret]'.
This prevents silent fallback to default credentials when secrets
aren't properly resolved by Nextflow's secrets system.

The method provides comprehensive error messages with troubleshooting
guidance for common secrets configuration issues.

Fixes issue where plugin would use default username 'sa' instead of
failing fast when workspace secrets were not accessible.
