Adds new tile on the admin home page with system data.

Also fixes the active users bug in the pie chart.

Two things to note here:

• at least when running pnpm dev, the progress bars for cpu and ram usage don't load properly at first, but work fine after a few seconds.
• some error appears in the terminal intermittently. It might be related the websocket being disconnected/reconnected, i'm not 100% sure.

Just threw up a review of this PR, got some questions about it.

Any updates?

[Pacodastre]

I'm getting back to it today. I'll update the PR when it's ready.

[DecDuck]

Looking good, just some final touches :)

Just *three things:

• I took a look and it seems like you can totally remove the acl properties for the systemManager, and then we can get right of the extra ACL fetch in the websocket route:

-      { callback: (systemData: SystemData) => void; acls: GlobalACL[] }
+      { callback: (systemData: SystemData) => void  }

-    this.listeners.get(userId)!!.set(id, { callback, acls });
+    this.listeners.get(userId)!!.set(id, { callback });

etc...

• We need to do a pushUpdate on connecting otherwise we have to wait until we get the first UI update
• Updating every 10 seconds seems a little slow, maybe something like 3 seconds?
