Component tests mounted without main.ts's bootstrap, so the $ver global
template helper (app.config.globalProperties.$ver = displayVersion) was
undefined — AppSidebar/AppHeroSection/MarketplaceAppCard tests failed with
"_ctx.$ver is not a function", blocking the release gate's ui-unit-tests
stage. Add a vitest setup file that mirrors main.ts via config.global.mocks
and wire it into vitest.config.ts.
