test: port the tests left as todo!() stubs

Replace the todo!() bodies with real ports. Four autoload-generator
tests now run for real; the rest stay #[ignore]d, but each ignore reason
now names the concrete missing symbol instead of a vague subsystem.

Production additions the ports need: the deprecated
AuthHelper::addAuthenticationHeader wrapper,
EventDispatcher::__set_dispatch_script_override as the seam for PHPUnit
onlyMethods(['dispatchScript']), and a define() stub in the shim.
