PD: fail query and update tests in the bench

Reproduce the PHP 8.4 startup warnings and inspect the referenced files under webman-framework/src/, including Config.php, Route.php, Route/Route.php, App.php, Context.php, and Http/Response.php. Start with the deprecated nullable-parameter reports, then run the benchmark's failing query and update tests. Done means the deprecated warnings are resolved and those benchmark tests pass.
