[FEATURE] Root NeoUI - Server list auto-join + blacklist

### Description

While the serverlist has generally been implemented, it's missing auto-join and server blacklisting.

### Proposed Solution

* Auto-join for when the server is full
* Server blacklisting so blacklisted servers don't show up in the normal list
* Bots counter
