[Sonarr] Custom Filter editor not themed on hover

[rg9400]

In Mass Editor > Filters > Custom Filters, the background when hovering over existing custom filters is not themed. Current CSS is below -- I can make a PR fixing it, but not sure which color best fits the style guidelines for themepark

.CustomFilter\/customFilter\/zBSMd:hover {
    background-color: #fafbfc;
}

Thanks. I mostly use hsla(0,0%,100%,.08) on hover. I think that should be fine there.
