feat(admin): Phase 4 质量词 Admin(平台单层) — QualityWord + 生成侧读配置(无配置回落) + 质量词页

后端:apps/ai QualityWord(stage/slot/text/sort/enabled)+ migration;services.py quality_words/quality_suffix,
4 个 builder 接入(person/model_tryon/storyboard/video)无配置回落原写死值零回归;adminpanel CRUD + 审计。
前端:adminApi quality 系列;Admin 质量词页(按 stage 分组卡 + 编辑模式开关 + 行内增改删 chip)。
测试:adminpanel 23 + accounts 22 = 45 单测过(CRUD/权限/生成读配置+回落/停用词不取);
无头 e2e _admin-p4.mjs 4 断言过 + 0 console error + live 库零残留;tsc+build 绿。
注:apps.ai 3 个 image_edit 路由测试失败为进场前既有(已 stash 比对 HEAD 同样失败),非本 Phase 引入。
