docs: broken images in several chapters (desktop path, localhost URLs, missing res/ files)

[auroraxo]

Describe the bug

Several markdown files in Python-100-Days reference images that do not load when browsing the repository on GitHub:

1. Absolute local macOS path committed into markdown:

   • File: Day46-60/47.深入模型.md (line 292):

     ![](/Users/Hao/Desktop/Python-100-Days/Day41-55/res/django-admin-login.png)

   • On GitHub this renders as a broken link because it points to the author's local desktop path. Day41-55/res/django-admin-login.png does not exist in the repository (HTTP 404).

2. Missing in-repo assets:

   • Day01-20/11.常用数据结构之字符串.md (line 5):
     <img src="res/day11/eniac.jpg" style="zoom:50%;">
     Target Day01-20/res/day11/eniac.jpg returns HTTP 404 (not in repo tree).
   • Day36-45/45.Hive实战.md:
     References res/QQ20220708-235815@2x.png and res/QQ20220707-195545@2x.png — neither file exists in Day36-45/res/ (both HTTP 404).

3. localhost URLs referenced in public markdown:

   • Day36-45/39.SQL详解之DQL.md: http://localhost/mypic/20211121135117.png
   • Day36-45/42.视图、函数和过程.md: http://localhost/mypic/20211121225327.png
   • These point to localhost and cannot load for any reader.

Steps to reproduce

1. Open https://github.com/jackfrued/Python-100-Days/blob/master/Day46-60/47.深入模型.md#L292
2. Open https://github.com/jackfrued/Python-100-Days/blob/master/Day01-20/11.常用数据结构之字符串.md#L5
3. curl -o /dev/null -w '%{http_code}\n' https://raw.githubusercontent.com/jackfrued/Python-100-Days/master/Day01-20/res/day11/eniac.jpg → 404
4. curl -o /dev/null -w '%{http_code}\n' https://raw.githubusercontent.com/jackfrued/Python-100-Days/master/Day41-55/res/django-admin-login.png → 404

Suggested fix

• Fix the local desktop path in Day46-60/47.深入模型.md and commit the missing screenshot.
• Restore or replace the missing images in Day01-20/res/day11/ and Day36-45/res/.
• Replace the http://localhost/mypic/... image URLs with the public CDN/repository URLs.

感谢回复 😄 不着急~

我先准备好了一个最小修复 PR：#1218 —— 把 39 和 42 两章里两个 http://localhost/mypic/... 图片链接换成了您 Gitee 图床 (jackfrued/mypic) 的公开链接（两张图都已验证 HTTP 200），只改动这两行，不动其他内容。

issue 里其余问题（Day01-20/res/day11/eniac.jpg、Day36-45/res/ 下两张 QQ 截图、Day41-55/res/django-admin-login.png 文件缺失，以及 47.深入模型.md 里那条 /Users/Hao/Desktop/... 绝对路径）需要您决定是恢复图片还是删掉引用，我没有擅自处理。

顺带一提：@Zach-X-Min 已经睡了，图片明天醒来应该就能看到了 😴
