Summary

🛠️🎨📱

The pull request adds a responsive sidebar to the kubepanel layout and fixes a style conflict between tailwind css and antd. It uses react hooks, antd components, and custom css to achieve the desired layout and appearance. It also deletes an unused file and adds some comments and configuration options.

Sing, O Muse, of the cunning code that resolved the clash
Of Tailwind and Antd, the mighty frameworks of the web,
How with skillful tweaks and comments they fixed the broken styles
And added a sidebar, like the gates of Troy, to the kubepanel.

Walkthrough

• Fix a conflict between tailwind css and antd by adding an id attribute and a comment to the body element (link), disabling the preflight feature and adding a #app selector to the tailwind classes (link), importing the reset.css from antd and overriding some default tailwind properties (link) in globals.css, and removing the overflow: auto style from the sider (link) in layout.tsx
• Delete the kubernetes.ts file as it is no longer needed (link)
