Non-existent filter lists/bad url's and indication of such in filter list UI

[Quijib0]

The other day I was looking through my filter lists to see what was going on with a TikTok filter list I had subscribed to about a year ago. In looking at the interface, there was listed a last updated time of the previous morning and a rules count. Went to follow the link to the list and it gave a 404 not found error. Was valid last time I checked when I set it up.

Anywho, the only way I figured out to check the link was when I was going through the dashboard logs and seeing no tiktok blocks (daughter uses it pretty frequently). This was odd because I would at least see about 10-15 domains blocked every 24hrs or so.

So, not sure if this has been brought up before, it would be good to have some sort of error notification whenever one of the DNS lists vanishes. As far as the UI was concerned, that list was there and all was fine when in reality it was actually gone.
