feat: implement runtime base url configuration

[mustaphaturhan]

🛠️ Fixes Issue

Closes #308

👨‍💻 Changes proposed

• Makes sections in the settings panel collapsible.
• Adds new server settings to change base url in the runtime.
  • We are sending a request to <input-url>/status endpoint after user changed the URL. It throws an error if the URL is not in a URL format, or it is not reachable, or doesn't respond in 5 seconds or doesn't return correct response. If we get a response, we are checking route and isochrone in available_actions. If they are not presented in the result, we also doesn't let the change of base url
• We are saving the changed base url to local storage. If user refresh the page, they will continue to see new base url they set.
• There is also a "reset base url" button in the panel. If user clicks it, the base url will return back to the value set in the VITE_VALHALLA_URL environment variable.

📄 Note to reviewers

I haven't given much thought to security but since everything happens in the user's computer, I don't think there will be a problem.
