feat(models): add Chinese verbose_name to all 74 models (Phase 4.0)

为所有 Django 模型添加 Meta.verbose_name 和 verbose_name_plural（中文表名），
覆盖 10 个 app 的全部 74 个业务模型。

Phase 4.0 范围：
- 仅 Meta 类级别中文名（用于 Django Admin、drf-spectacular OpenAPI title、错误信息）
- 字段级 verbose_name= 和 help_text= 留待 Phase 4.1（待 PM 补全 DATA_MODEL 后同步）

变更：
- 20 个 models 文件改动（每个模型 +2 行）
- 8 个 0002/0003 迁移文件（Meta options 变更）
- apps/tenant/migrations/0001_initial.py（之前漏生成的 tenant 模型迁移）

manage.py check: 0 issues。
