A11y:
- Add alt_text field to MediaAsset and ContentBlock (WCAG 2.1 AA 1.1.1)
- Expose alt_text in MediaAssetSerializer and ContentBlockSerializer so
frontends can render <img alt="..."> and <video aria-label="..."> correctly
- Migration 0002 adds the two alt_text columns
i18n:
- Add LocaleMiddleware to MIDDLEWARE stack (after SessionMiddleware per Django docs)
- Add LANGUAGES = [("de", ...), ("en", ...)] and LOCALE_PATHS = [BASE_DIR/"locale"]
- Add USE_L10N = True
- Seed locale/de/LC_MESSAGES/django.po and locale/en/LC_MESSAGES/django.po with
translations for all user-facing API strings (upload errors, notification titles)
Tests (tests/a11y/test_a11y_i18n.py):
- alt_text field round-trip on MediaAsset and ContentBlock
- Serializer exposes and accepts alt_text on create, list, PATCH
- LANGUAGES/LOCALE_PATHS/LocaleMiddleware settings assertions
- Accept-Language header switching smoke test against /api/v1/notifications/
