feat: Users online and LLM's running

[RealMrCactus]

Is your feature request related to a problem? Please describe.
Not really could help with a problem though, showing the users currently active and how many LLM's are running could help users show when performance is going to be low when you have a lot of users like me.

Describe the solution you'd like
Little icons with numbers next to them on both desktop and mobile somewhere that show how many users and llms are running/online

Describe alternatives you've considered
None
