fix(ketones): offer ketone logging in the catalog and as a checkup

Ketones joined in v1.47.2 without their two sibling lists. The metric
catalog treated them as connectable and sent a user without readings
to the integrations page, where nothing delivers ketones; they now
count as manual-only and the row offers "Log ketones". And a checkup
could not be tied to ketones, so a "measure ketones" reminder never
resolved on its own; ketones are now a reminder target next to blood
glucose, with a label in all ten locales. A catalog test also holds
every metric that cannot be connected to a way to log it.
