Introduce a shared PageAuthGate (header + tile skeleton) and adopt it on the
top-level pages that flashed a lone centered spinner while auth resolved:
mood, measurements, achievements, illness, mental-wellbeing, checkups, cycle,
and the labs / medications / custom-metrics / illness detail routes. The
auth-resolving frame now reserves the page geometry instead of snapping in
after a spinner.
Move the PHQ-9 / GAD-7 screener off `/insights/mental-wellbeing` to a
top-level `/mental-wellbeing` route so it no longer borrows the Insights
tab strip and layout shell. The page now uses the standard module-page
frame at the wider content width the other module pages use.
Replace the standing screening disclaimer block and the opt-in/private
line in the header with an info icon after the page heading whose
hover/focus tooltip carries the screening-not-a-diagnosis note. Drop the
now-orphaned `disclaimer` / `optInNote` strings across all six locales
and add the `infoTooltip` string in their place.
The questionnaire, scoring, severity result, PHQ-9 item-9 crisis-resource
handling, focus-on-submit, and 44px touch targets are unchanged. Repoint
the module nav entry and the registry comments at the new route.
