feat(M1): 数据模型迁移 + GS1 GPC 食品分类 + 单位字典
- migrations/0001_init: 全部核心表(product/food_detail/product_msrp/product_source/brand/manufacturer/category/category_schema/unit/attribute_definition/product_image/merge_log) + 索引(gtin唯一/name trigram/JSONB GIN/category ltree/tsvector) + tsvector/updated_at 触发器
- 0002_seed_units: 单位字典(与 units.py 一致, 含中文别名) + 常用营养参数定义
- 0003_seed_categories: 食品品类骨架(GS1 GPC 映射 + 自建中文树, ltree) + 品类参数模板(营养基准 per_100g/ml)
- CI 增加 migrations job: 用 postgres service 跑 migrate up + down 验证可逆
- 本地实跑 up/down/re-up 全部通过
