Health check endpoint about pufferpanel

[LordRalex]

The issue is that in the grand scheme of how healthchecks should work, that is exactly what it should be.

If you are doing checks like this, ideally, you'd actually move the database to be it's own container, and so it would have it's own healthcheck. Which ensures that the DB part of the "service" is online.

I don't really want to add a method that does DB calls that isn't behind auth or otherwise requires specific data to get past. While this won't hurt anything, it's not ideal.
