Consider improvements to logging

Hi, I've been looking into how to get connection auditing out of a Sunshine host, but it seems like this is somewhat lacking currently.

As far as I can tell, in Info verbosity currently, you can tell when a connection is established or disconnected, but that's about it. Debug is way too verbose for most people to run all the time, but at least it captures the client IP address. Not the paired device name, though.

For a remote access tool like this, it should be very easy to determine whether a client is connected, which paired device it is, and other info such as the IP address. And if I'm mistaken with any of this, please let me know!

If I may make a few suggestions:

• Both the Client IP address and paired client name should be logged in at least Info verbosity on connect/disconnect/reconnect
• Connection state with client names should be visible in web UI
• Paired devices list should have a last-connection date, to possibly make it easier to prune old clients from the list
• Web UI access is Info logged on 403, but not 20x. I don't see the client IP in Debug verbosity either.
• It's good that the Windows tray icon shows whether there is an active connection, but it would be nice to also show the client name in the tooltip or right click menu
• It would be nice for there be an option to display a toast on client connect/disconnect
• It would be nice to expose the client name and IP address as environment variables when invoking a script from Command Preparations

With that said, I've been using Sunshine since about 2023 and have been very happy with it. Thank-you for all the hard work!
