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.

+
+| Field             | Value                                              |

+
+## 3. Rationale
+
+[Why is the deviation technically acceptable in this specific case?]
+
+Possible rationales:
+- Hardware access requires type conversion
+- Compiler-specific behaviour is defined and tested
+- Alternative implementation would be disproportionately complex
+- Rule is not safety-relevant in this context
+
+**Specific rationale:** [Fill in here]
+
+## 4. Risk assessment
+
+| Aspect                    | Assessment                                    |
+|---------------------------|-----------------------------------------------|
+| Safety relevance          | [None / Low / Medium / High]                  |
+| Fault potential           | [Description of potential faults]             |
+| Mitigation                | [Which tests / measures cover the code]       |
+| Residual risk             | [Assessment of the residual risk]             |
+
+## 5. Reference to deviation permit
+
+| Field                 | Value                                         |
+|-----------------------|-----------------------------------------------|
+| Permit exists         | [Yes / No]                                    |
+| Permit ID             | [PER-XXX or "n/a"]                            |
+
+If no permit exists: this deviation is a single-case approval.
+
+## 6. Approval
+
+| Field             | Value                                              |
