feat(admin): minimal console for KB content operations

apps/admin 独立应用：X-Admin-Token 鉴权（空=全部路由不注册=404）、实体/规则
维护与状态机流转、发布编排（publish/archive → 规则缓存 invalidate +
retrieval invalidate_cache 双失效）、素材登记与审核（tryon_ready 门禁透传）、
缺口看板（T-P2-09，FR-ADM-01~05）。V1 共享令牌鉴权，无角色无审计字段，
操作留证靠 structlog request_id。

测试：单测 tests/unit/test_admin_app.py（10 例：空令牌 404、错/缺/非 ASCII
令牌 40100、正确令牌 200 假服务、发布编排接线、幂等重放无副作用）；
集成 tests/integration/test_admin_console.py（5 例：顾问全流程不碰客户端
API、双失效副作用可观察、非法跃迁 40900、素材审核门禁、缺口看板排序、
令牌 401）。483 单测 + 43 集成全绿；ruff/mypy/lint-imports 全绿。

偏差说明：
1. packages/retrieval.repo.list_gaps 有缺陷：对 select(KbGap) 的结果调
   .mappings()，行键是实体名而非列名，GapSummary(row) 取 row.gap_id 必然
   AttributeError（该路径无既有测试覆盖，接真库即暴露）。packages/** 本
   任务禁改，故缺口查询在 apps/admin/routers/gaps.py 以等价 SQL 自实现
   （hit_count 降序、同频次按 last_seen_at 降序、limit/offset 语义一致）；
   建议合并阶段修复上游后切回 retrieval.list_gaps。
2. 实体 transition 的 target 收全量四态（任务文档示例仅列 reviewing/
   published/archived）：按任务测试要求 published→draft 必须返回 40900
   （状态机语义冲突）而非 schema 422；draft 作为目标由服务层跃迁矩阵恒拒。
3. 规则路由以 rule_key 为路径参数（任务文档写 /rules/{id}，但 RuleService
   全程以 rule_key 寻址，无按数字 id 的接口，以代码为准）。
4. 发布编排触发面含 archived（撤稿）：依据 retrieval.invalidate_cache 的
   自身契约「发布/归档知识后调用」，比文档字面的「发布成功后」多了撤稿
   方向；reviewing 等其余状态不触发。
5. updated_by/author 记 "admin-console"：V1 共享令牌无操作者身份，字段
   留渠道来源；运营账号体系属 V2（见包 docstring 的升级路径）。
