Personally I find the notifications.client-uri and notifications.server-uri configuration options confusing, for the following reasons:

1. The default values point to localhost, which is ambiguous in a multi-server setup.
2. The protocol for notifications.client-uri is ignored, and ws or wss is used instead.
3. "Server" is ambigious because the Aphlict server is actually composed of two separate server components (one HTTP server for receiving notifications and another WebSockets server for handling client connections).

As such, I have added to the existing documentation to clarify some of these ambiguities. Additionally, I have rename notifications.server-uri to notifications.admin-uri for clarity (even this name is still a little ambiguous, but feels slightly better).

Briefly tested the Aphlict functionality to make sure I hadn't missed anything.
