fix(dl): 落地页底图+logo 纳入 git → 修生产 /media 404 毛坯 (#97)

## 背景
用户反馈浏览器落地页仍是「毛坯」(裸黄底、缺优惠券卡/价格卡/logo)。

## 真因(实测线上)
`https://app-api.shaguabijia.com/media/dl.html` 的 **HTML 早已是完善版且已部署**,但它引用的两张静态图被 `.gitignore` 的 `data/media/*` 规则挡在库外、从未随部署进生产 `/media`:

| 资源 | 线上 | 本地/git |
|---|---|---|
| `/media/coupon-page-bg.png`(底图:优惠券卡+跨平台比价价格卡) | **404**(22B `{"detail":"Not Found"}`) | 之前被 gitignore |
| `/media/sb-brand.png`(logo) | **404** | 之前被 gitignore |
| `/media/shaguabijia.apk`(对照) | 200 ✓ | — |

→ 两图加载失败 → 页面回退裸黄底 = 毛坯。

## 改动
照 `dl.html` / `taobao_landing.jpg` 既有白名单写法,把这两张图加进 `.gitignore` 例外并入库。
- `.gitignore`:`!data/media/coupon-page-bg.png`、`!data/media/sb-brand.png`
- 入库两图,md5 与原型一致(coupon-page-bg `f2adf28a` / sb-brand `e5b6e004`)

**无代码/HTML 改动**(dl.html 本就对齐原型,见上一 commit `6d4cbc8`)。

## 部署后生效
合并并部署本分支后,生产 `/media/` 即含这两图,落地页恢复完整。对应 6-29 UI 对齐 #10。
