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

+| 字段 | 类型 | 说明 |
+|---|---|---|
+| `app_id` | string | 穿山甲应用 ID（改了需冷启才生效，SDK init 一次性读） |
+| `reward_code_id` | string | 福利页激励视频位 |
+| `compare_draw_code_id` | string | 比价 Draw 代码位 |
+| `coupon_draw_code_id` | string | 领券 Draw 代码位（与比价共用同一位，靠 `feed_scene` 区分收益） |
+| `reward_enabled` | bool | 福利激励视频开关 |
+| `compare_ad_enabled` | bool | 比价广告开关 |
+| `coupon_ad_enabled` | bool | 领券广告开关 |
