docs: reorganize api docs into categorized subdirectories and fill missing docs

- Categorize 77 existing api docs into 16 business-domain subdirectories
  (auth/ad/wallet/coupon/compare/savings/signin/tasks/invite/user/
   device/platform/intent/meituan/other) plus admin/ and internal/
- Split admin/ into 7 sub-resource subdirectories (auth/users/wallet/
  withdraws/feedbacks/admins/ad) with 4 single-file docs at root
- Create 21 new docs covering 28 previously undocumented endpoints:
  ad/watch-report, wallet/transfer-auth (3 endpoints), coupon/session+
  stats+completed-today+prompt (7), invite/me+invitees+bind+landing-track,
  user/onboarding (2), platform/flags+ad-config+app-version,
  intent/step+precoupon/step, analytics/events, order/report,
  report/submit+records, feedback/config+records, trace/finalize
- Add mock request/response JSON examples to all new docs
- Create docs/README.md with full category index for LLM navigation
- Update docs/api/README.md: fix all links, add new endpoint rows,
  replace "no doc" markers with actual links
- Fix back-navigation links (./README.md -> ../README.md or
  ../../README.md) in all moved files

+# POST /admin/api/users/{user_id}/status — 封禁/解封用户
+
+> 所属:Admin·用户 组（前缀 `/admin/api/users`） | 鉴权:Bearer admin_token（角色:`operator`,`super_admin` 恒通过) | [← 返回 API 索引](../../README.md)
+
+## 入参
+- 路径:`user_id`(int)
+- **application/json**:
+| 字段 | 类型 | 必填 | 说明 |
+|---|---|---|---|
+| `status` | string | ✓ | 目标状态,枚举 `active`(解封)/ `disabled`(封禁);注销 `deleted` 不走此接口 |
+
+## 出参
+响应 `200`:`OkResponse` = `{ "ok": true }`
+
+## 错误码
+- `400` 已注销账号不可改状态(目标用户当前 `status == deleted`,`detail: "已注销账号不可改状态"`)
+- `401` 未带/无效/过期 admin token、管理员被禁用(头带 `WWW-Authenticate: Bearer`)
+- `403` 角色不足(需 `operator` 或 `super_admin`)
+- `404` 用户不存在(`detail: "用户不存在"`)
+- `422` `status` 非 `active`/`disabled` 枚举 / 缺字段 / `user_id` 非整数
+
+## 说明
+- 业务写(改用户状态)与审计写在同一事务原子提交:改了就有痕、有痕就真改了。
+- 写操作记审计 [admin_audit_log](../database/admin_audit_log.md):`action = user.status.set`,`target_type = user`,`target_id = user_id`,`detail = {before, after}`,并记录操作 IP。
+- 关联用户表 [user](../database/user.md)。
