Commit 56db30e made Message generic, but left EmailMessage inheriting from bare MIMEPart. Propagate the same type parameters to EmailMessage so it is typed consistently, and add a regression test case covering the generic EmailMessage behavior.

Commit 56db30e made Message generic and switched get_body() and iter_parts() to return MIMEPart[_HeaderRegistryT]. That dropped the second type parameter, so the header parameter type defaulted to Any. Preserve both type parameters in the return types and add a regression test covering get_body() and iter_parts().
