Changes

• Fixed a number of issues surrounding how the group request actions are handled.
• Moved confusion profiles to a standalone menu item for now. We should revisit this sidebar menu in the future and categorize things more intuitively.

Testing

• Start the app, mess around with joining, approving requests for, and leaving groups.
