Registration goes through core's package-level facades: SetAppRouters for
the routes, migration.ForApp for the schema, and seed.MenuSpec/ApiSpec
for the menu rows - none of which requires importing the host.
The menu component is spelled apps/order/order/index. The frontend tells
a packaged view from a built-in one by that first segment alone, and
getting it wrong is silent: the page falls back to the not-installed
placeholder while the console names a src/views path that was never going
to exist. The tests assert that prefix, that every Parent reference
closes, and that every ApiCode resolves - the three ways a menu graph is
wrong without anything saying so.
