Settings Page with Dark Mode and Availability

[sahedw]

Create settings icon with right positioning. Create the page/route with next.js. Track user selected availability option so that it stays this way and only displays what the user wants to see. Add dark mode and toggle function. Adapt color, texts and icons to dark mode. Add tooltip for availability settings option.

great work the only thing that doesn't work is the settings page. because an error is issued if you want to open it.

Fixed it, thanks!
