refactor(i18n): rename vorlagen/ -> templates/, *-vorlage -> *-template

Final German naming cleanup in dev-process:
- vorlagen/                            -> templates/
- vorlagen-word/                       -> templates-word/
- tools/generate_word_vorlagen.sh      -> tools/generate_word_templates.sh
- *-vorlage.md / *-vorlage.docx        -> *-template.md / *-template.docx
- Review-Protokoll-vorlage.*           -> Review-Minutes-template.*
- angebot-vorlage.*                    -> quote-template.*
- angebot-beispiel.html                -> quote-example.html

All references in README.md, toolstack/toolstack.md, build_word_template.py,
and generate_word_templates.sh updated. The master Word style template
(slohmaier-doc-template.docx) was already English-named.

The dev-process repo is now fully English in both content and structure.
