Fix vimeo#11721 Psalm validates some sprintf/printf formats by calling them with dummy values. For .* precision placeholders that used empty strings, PHP 8 raises a false ValueError and Psalm reported InvalidArgument. Validate complex * width and precision placeholders with integer dummies before falling back to the generic return type. Add regressions for %.*f, positional variants, and related arity errors.

Update psalm-baseline.xml for vimeo/psalm#11729. The sprintf precision placeholder fix removes several Missing* baseline entries in this fixture project, so the baseline needs to be regenerated with the current Psalm branch.
