Subject: [PATCH] Webapp: count only mapped frameworks in the home-page
 headline

The home page added every registry to the framework list, mapped or not, and
summed every registry's controls into "Registry Controls". A registry that
lands before its rows (NIST AI 600-1 in #187) would have shown 27 frameworks
against the README's 26 mapped, and added 211 unmapped controls (+19%).

Frameworks now come from the mapping rows alone, and the controls total only
counts registries a row cites. No change to today's numbers: all 26 registries
are mapped. New webapp test pins the hero to stats.json's frameworks.mapped.
