Smooth out the jarring visual pop when loading skeletons are replaced
by real content. Only animates after an actual skeleton was shown —
cached data still renders instantly with no delay.
Remove the individual session journey page and make the live visitor
count a static indicator. Prepares for the new aggregated User Journeys
feature (v0.17).
SiteNav now lives in the [id] layout instead of each page, so it stays
mounted during route transitions. Switching between Dashboard, Uptime,
Funnels, and Settings no longer flashes a full-page skeleton.
