feat(generators): widen DepartmentNameGenerator data, fix de/en mismatch (#192)

## Summary
- Reported as a missing generator (\`DepartmentNameGenerator\`), but it
already exists at
\`datamimic_ce/domains/common/literal_generators/department_name_generator.py\`
- registered automatically via \`auto_register_generators()\` (location
+ naming convention, no manual export needed).
- The actual gap: a thin word list (no Engineering/Finance/Customer
Support/Operations/R&D) and a de/en mismatch - the German list carried
untranslated English words ("Accounting") and was missing a
"Manufacturing" counterpart.
- Widened both locale lists to the same 13 departments, properly
translated for de.
- Added the missing unit test (none existed - only incidental DSL
coverage in \`test_large_count/test_generators.xml\` and the demo
\`organization.xml\` that exercises generation without asserting on
values).

## Test plan
- [x] New unit test (\`test_department_name_generator_support_locale\`,
\`test_department_name_generator_unsupported_locale_falls_back_to_en\`).
- [x] Existing DSL fixture using the generator still passes.
- [x] mypy/ruff clean.
