CategoryList

JSON fixture for CycleUni's admin Category (college) bulk-import feature.

• Target API: POST /api/v1/admin/categories/bulk/ (adminapi.views.AdminCategoryBulkImportView, staff-only)
• Request body: {"action": "preview" | "apply", "items": [...]} — send categories.json's items array as-is
• Matching key: slug (unique on the Category model) — re-importing is idempotent; unchanged rows are skipped, differing rows are reported as modified
• Field shapes: canonical title/description are in Chinese (matching this project's actual seeded data in core/migrations/0002_seed_categories.py, not the model docstring's English-canonical description), translations.en holds the English variant

Contents: the 8 colleges already seeded by core/migrations/0002_seed_categories.py (worded identically, so importing against a fresh database reports them as unchanged) plus 4 additional colleges (agriculture, arts & design, education, dentistry). Tested end-to-end against the live endpoint in CycleUni-BE/tests/test_bulk_import_fixtures.py, including the new/modified/unchanged diff paths.
