Add a Input / Output diagram to show Privacy and security behavior

:bulb: Idea

• Enhance the documentation with privacy and security relevant information and Warnings.
• Add setup Wizard for the ntfy server that helps to properly setup ntfy and do not forget important details.

:notebook: Behind the Idea I'm privacy driven. May a bit more than others. But Im a selflearner on Linux, Networking and currently on OpenWRT. I'm scepti on Google and microsoft. Cause of that, I play with the thought about using ntfy replacing Google push and using unified push. therfore I have to grant ntfy Internet access. While Playing around I miss the feeling that I configured everything properly.

• Is only unly unified push accessible from internet? No login, no push message. Could I limit the network access to only accept more features from 192.168.. Or do I need a firewall for that?
• There is the information, I could create an admin user. For me it is not clear why there is no default admin set up. It's irritating and I assume it could be more secure without it?
• On the Android app I could setup the server, but It seems I do not get any information if the connection works or get an error information if not.

1) UnifiedPush messages are just ntfy messages sent to a special topic in a special format. You cannot limit ntfy features by IP address (since there's little difference between a non-UnifiedPush message and a UnifiedPush message) 2) I'm not sure what you mean. There's no default admin because we don't know what you want the admin username/password to be. You don't even necessarily need an admin account at all (for example, if you set up the server default access as "read-write") 3) if the Android app has problems connecting to the server, you will see it says "reconnecting." You can also send a test notification from the 3-dot menu on a specific subscription page
