feat: add #btn-toggle-dark botton to toggle dark mode

- Switch dark theme to bulmaswatch/darkly, since bulma-prefers-dark highly relies on `@media: (prefers-color-scheme: dark)` tag
- Add a playerman handler to toggle shikwasa theme[1]
- Use localstorage to store user's preference[2]
- Fix a typo: SystemDarkmodePrefrence => SystemDarkmodePreference

[1]: Modified from https://github.com/jessuni/shikwasa/blob/main/pages/public/index.js#L208
[2]: Took inspiration from https://blog.skk.moe/post/hello-darkmode-my-old-friend
