fix: correct SiteController view return types, drop ViewContract alias

An automated return-type pass aliased the view contract as ViewContract
to avoid clashing with the imported View facade, but left four methods
(curatedOnboarding, language, redirectUrl, followIntent) typed against
the facade instead of the contract. That threw a TypeError on
/auth/sign_up.

Convert the four View::make() calls to the view() helper, drop the
facade import, and use a single Illuminate\Contracts\View\View import
for all return types.
