Simple diagnostic tool

[bendauphinee]

Is your feature request related to a problem? Please describe.
I run a portable field base station, which I use on established position stakes. Being portable, this means I move it, take it home with me when I'm not on a site, that kind of thing. The problem I've run into a few times now is that when booting up the base station, it refuses to connect properly to my GPS unit (ZED-F9P), and I lose up to an hour rebooting and tinkering until it eventually connects properly. This despite seeing a solid PPS lock on the GPS unit.

Describe the solution you'd like
A simple diagnostic page or tool that shows the current state of the GPS signal, the NMEA string being received from it, if the str2str_tcp service is properly up and able to connect, and whatever other basic diagnostic data would be useful to know that the chain from antenna to service is working correctly or something needs to be fixed.

Describe alternatives you've considered
Fix the str2str_tcp service per issue #333 to be more resilient. This still wouldn't help diagnose connectivity or signal issues imho.

Could you test with Debian 12?

You could check the status page. If there is a problem with the F9P link, you should see no sat levels.
