fix: resolve test failures across translations, contact form, and vitest config

- Add 18 missing translation keys to all non-English locales (de, es, fr, it, ja, nl, pt) with English fallback values
- Fix contact form submit test targeting prefix input instead of given_name
- Exclude .next/ build output from vitest to prevent Playwright spec conflicts
