Add 4-arg overloads to App.register_<entity>() that call configure_entity_()
and push_back in a single function. Codegen defers App.register_<entity>(var)
emission until finalize_entity_strings(), which then emits a single combined
App.register_<entity>(var, name, hash, packed) call instead of the previous
two-statement pair (App.register_X(var); var->configure_entity_(...)).

No behavior change. configure_entity_ remains protected on EntityBase; the
Application class is now a friend so the new overloads can call it.
