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.
Replace manual useState/useEffect fetch patterns with SWR hooks so
cached data renders instantly on tab revisit. Skeleton loading now
only appears on the initial cold load, not every navigation.
New hooks: useFunnels, useUptimeStatus, useGoals, useReportSchedules,
useSubscription — all with background revalidation.
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.

Dashboard, Uptime, Funnels, and Settings now use a consistent
underline tab bar with orange active indicator, matching the
existing panel tab design language.
Use page paths, referrer URLs, item names, and composite location
keys instead of array indices. Prevents stale-row glitches when
lists are filtered or reordered.
