fix(ssr): remove conflicting RouteMixin that caused 'Cannot read properties of undefined (reading index)'

RouteMixin received the full Inertia page object instead of page.props,
producing a Ziggy config without routes. ZiggyVue already provides the
route() function with the correct config, so the duplicate mixin is
unnecessary.
