revert(ptica): restore old Section1-6 analysis view as default route

The ПТИЦА dark cockpit (made default in ba05a4c) is being redesigned from
scratch. Roll the live /site-finder/analysis/[cad] route back to the original
AnalysisPageContent (Section1-6) so pilots/investor see the stable design while
the new cockpit is reworked.

Non-destructive: only the route's rendered component + metadata/fallback are
reverted. All ptica code stays in the repo and the cockpit remains viewable at
/__preview/ptica-full for redesign reference.
