✨ Feature parity: Add a Random Subreddit button

[Seladorrr]

How does this feature work on Reddit?

Reddit has a 'Random Subreddit' feature (https://www.reddit.com/r/random/) that sends users to a random subreddit. It's a fun way to discover new communities and content.

Describe how this could be implemented into Redlib

Add a '🎲 Random Subreddit' button to the Redlib UI (for example, next to the search bar or in the navigation menu). When clicked, it should redirect the user to a random subreddit page. This should respect user settings for SFW/NSFW content. Optionally, display a short animation or fun message when the button is clicked for extra delight!

Possible implementation steps:

• Backend: Add an endpoint that fetches a random subreddit (optionally filtered for SFW/NSFW preference).
• Frontend: Add the button to the UI, and handle the redirect/animation.

Describe alternatives you've considered

• A keyboard shortcut to jump to a random subreddit.
• Option to limit randomization to subscribed or popular subreddits only.
• Daily "Surprise Me" notification or prompt.
