fix: merge main branch and renumber migration 027→037

Resolve 3 merge conflicts and renumber the automation_hooks migration
to follow main's migration chain (036_add_document_translation_fields).

Conflicts resolved:
- app/api/__init__.py: add automation_router alongside main's new routers
- app/utils/settings_service.py: add automation_hooks_enabled alongside compliance_enabled
- tests/conftest.py: add AutomationHook alongside AuditLog/ComplianceTemplate imports

Migration renumbered:
- 027_add_automation_hooks → 037_add_automation_hooks
- down_revision: 026_add_scheduled_jobs → 036_add_document_translation_fields
