feat(dashboard): surface sleep, steps, glucose and vorsorge by default

The sleep, steps and glucose strip tiles shipped default-hidden even
though their modules are on by default and rich data flows in from the
sync integrations, so accounts had to hunt through Settings to see them.
Flip the three strip tiles to tileVisible:true and the vorsorge chart-row
card to visible:true, matching the VO2max precedent: each tile self-gates
on having data, so empty accounts keep a clean dashboard. Chart rows for
the three metrics stay off — those charts live on the /insights sub-pages.

totalBodyWater, boneMass and oxygenSaturation stay hidden: they carry as
catalogue ids for the iOS layout round-trip only and have no web render
path, so a flip would surface nothing. Note that at the splice point.

Update the silhouette skeleton and layout default tests for the new
counts.
