fix(web): resolve 7 TypeScript errors and 2 failing test files

Add vitest/globals types to web tsconfig to fix TS2593 errors in 7 test
files. Fix pricing and subscription test mocks to include all required
lucide-react icons and module dependencies (payment-api, auth-store,
next-intl, i18n/navigation).

All 66 test files now pass (593 tests), typecheck clean, lint clean.
