fix: loghi insanitylab estratti dal pdf figma al posto dei loghi template

- logo-dark.png (600×108) e logo-light.png (600×342) ora estratti da
  FigmaDoc/Homepage.pdf via pdftoppm 300dpi + ImageMagick, con alpha
- scripts/extract-logos.sh: pipeline riproducibile e idempotente (md5 stabile)
- asset-map.json: rimossa sezione fallbacks ../Dati (fonte errata PROWESS++)
- apply-asset-map.mjs: commento pipeline aggiornato a 4 step
