Frontail is abandoned

[rkoshak]

Issue information:

There was a recent thread on the forum pointing out that Frontail has not only not received any updates for some years but also has more than one pretty significant known vulnerabilities. Assuiming we don't want to take over for Frontail development and since we don't yet have a native log viewing service (though I think the core changes are made and we mainly just need the MainUI) we should consider whether it makes sense to switch to an alternative in the mean time.

An alternative mentioned on that thread is https://github.com/logdyhq/logdy-core though I'm sure it's worth doing a survey to see what other alternatives there are. I can say that logdy looks a lot more capable compared to Frontail.
