Reduce sonar issues in server.py

What does this MR do and why?

• Consolidate modded installs to their own class. This will allow for maintainability and scalability in the future
• Reduce cognitive complexity of server starts, server updates, backups.
• Use proper catching on errors/reraises
• While cleaning up fix regex that was problematic for update center. Sonar wanted it changed and I realized it was logically flawed while doing that.
• Append _ to delineate methods that should only be called in server.py...maintainability.
• Move much of the backup and update logic to their existing classes.
• Complete TODO that was previously accepted where terminal websockets were being sent to ALL users who had access to the server when in reality we only want users with access to the server who ALSO have terminal permissions to be able to access that websocket communication.
