fix(frontend): stop MSK breaking the Console Home resource count

Console Home counted every available service through the generic resource
list, but MSK and MSK Connect are available through their own pre-SPI pages
with no adapter behind /resources, so each answered 501 and the Resources tile
read "Resource load failed". Service descriptors now say whether the generic
list serves them (listable, true when an adapter is registered), and Console
Home counts only those; the MSK cards still link to their pages.
