fix: use correct short_name for base recipe links in English and edit pages

- Use English short_name for base recipe links when viewing English recipes
- Fix edit page to use /rezepte/edit/<shortname> instead of /{data.lang}/edit/<shortname>
- Ensures base recipe reference links work correctly in both languages
