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/withdraws/{out_bill_no}/refresh — 单笔提现重试查单
+
+> 所属:Admin·提现 组（前缀 `/admin/api/withdraws`） | 鉴权:Bearer admin_token（角色:`finance`，`super_admin` 恒通过） | [← 返回 API 索引](../../README.md)
+
+对单笔提现单调微信查单并归一化:`SUCCESS`→`success`；`FAIL`/`CANCELLED`/`CLOSED`→退款+`failed`；查到 `WAIT_USER_CONFIRM` 视为用户放弃（`cancel_if_unconfirmed=True`），撤单+退款；`ACCEPTED`/`PROCESSING` 等仍在途则保持 `pending`。已是终态的单直接返回、不再查。
+
+## 入参
+- 路径:`out_bill_no`（string） — 商户提现单号
+- body:无
+
+## 出参
+响应 `200`:`WithdrawOrderOut`（归一化后的最新提现单）
+
+**WithdrawOrderOut**
+| 字段 | 类型 | 说明 |
+|---|---|---|
+| `id` | int | 提现单主键 |
+| `user_id` | int | 所属用户 |
+| `out_bill_no` | string | 商户提现单号 |
+| `amount_cents` | int | 提现金额，单位:**分** |
+| `status` | string | 单状态（`pending` / `success` / `failed`） |
+| `wechat_state` | string \| null | 微信侧转账状态 |
+| `transfer_bill_no` | string \| null | 微信转账单号 |
+| `fail_reason` | string \| null | 失败/退款原因 |
+| `created_at` | datetime | 创建时间（ISO 8601 UTC） |
+| `updated_at` | datetime | 更新时间（ISO 8601 UTC） |
+
+## 错误码
+- `401` 未带/无效/过期 admin token、管理员被禁用（响应头带 `WWW-Authenticate: Bearer`）
+- `403` 角色不足（需 `finance` 或 `super_admin`）
+- `404` 提现单不存在（`detail="提现单不存在"`）
+- `503` 微信支付未配置（捕获 `WxPayNotConfiguredError`，`detail="微信支付未配置"`）
+
+> 注:微信查单本身失败（非未配置）时不抛错、不改状态，单保持 `pending` 等下次重试，故无 `502`。
+
+## 说明
+- 调用底层 `app.repositories.wallet.refresh_withdraw_status(..., cancel_if_unconfirmed=True)`（内部调微信查单/撤单/退款并 commit）。
+- 写操作记审计 [admin_audit_log](../database/admin_audit_log.md)（`action="withdraw.refresh"`，`target_id=out_bill_no`，`detail` 为 `{status, wechat_state}`，含触发管理员与客户端 IP）。
+- 关联 [withdraw_order](../database/withdraw_order.md)。金额单位为分。
