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 Co-authored-by: christianlouis <361235+christianlouis@users.noreply.github.com>

"""Internationalization (i18n) and localization (l10n) utilities.

Provides a JSON-based translation system for the DocuElevate UI with:

* **77 supported languages** covering European, Asian, Middle-Eastern, African, and other languages
|

* Browser ``Accept-Language`` detection with cookie & user-profile persistence
|

* AI-powered fallback translation via the configured LLM provider
|

* Locale-aware date, number, and file-size formatting helpers
|

* Jinja2 integration via a ``_()`` global function
|

|

Language resolution order:
|

1. User profile ``preferred_language`` (persisted in DB)
|

2. ``docuelevate_lang`` cookie
|

3. ``Accept-Language`` HTTP header
