Changelog

1. New ak_vendor/compliances/dora.py with 15 entries mapping to Regulation (EU) 2022/2554 articles, including a DORA dataclass and DORA_DATA lookup dict keyed by ID.
2. create_dora() added to the regulatory report builder in ak_vendor/report/report.py; DORA exposed on the report's regulatory section.
3. DORA section added to ak_vendor/templates/report_template.html after the SAMA block.
4. Japanese translations updated in ak_vendor/locale/ja/LC_MESSAGES/django.po with new DORA strings (untranslated — to be filled in separately).
5. Tests: new tests/test_dora.py covering the data catalog, DORA class, and DORA_DATA dict; tests/test_compliance_data_uniqueness.py updated to skip code-uniqueness check for DORA (intentional multi-entry-per-article design) and to validate title/url fields across all compliance modules.
