feat(sasch40): authentic 3 sisters portraits, 9:16 responsive stage with medieval ornaments, and hotspot fixes

- Recreate 16-bit LucasArts portraits for Saskia, Maja, and Miriam matching real-life source photos
- Add 3 sisters showcase in Act II intro modal and golden portrait badges on goal platforms
- Fix Act III background scaling: lock scene to 9:16 aspect ratio with medieval ornamental side borders and corner brackets
- Ensure 100% full background visibility with zero cropping and lock hotspot buttons to image features across all screen sizes
- Fix cache issue by referencing schankraum_v5.jpg with cache buster query
- Re-position NAT button to feet (top: 70%) and Mario button to knees (top: 79%) to eliminate face occlusion
