fix(3001-shop,3002-checkout): restore workspace dependencies

Fixed failing e2e-next tests by reverting nextjs-mf dependencies from
fixed version '0.0.0-next-20250701105507' back to 'workspace:*' in:
- apps/3001-shop/package.json
- apps/3002-checkout/package.json

This resolves module loading issues where the apps couldn't find
the nextjs-mf patches directory, allowing proper Next.js federation
to work correctly.
