Fix auto-login failure when DATABASE_URL uses default port 3306 (#36)

* Initial plan

* Fix auto-login by casting port to int before comparison

Cast port to int before strict comparison to handle type coercion from rawurldecode.
This ensures the default MySQL port 3306 is correctly detected regardless of type,
preventing session key mismatch between storage and lookup.
