feat: 16:9 landscape canvas + F-key presentation mode

- image prompt: vertical 9:16 → landscape 16:9 cinematic, scene fills
  canvas with bottom dialogue band and horizontal choice row
- image-client: pass size=1792x1024 hint (provider honors it → output is
  now exact 16:9 instead of the model's default 1.75:1)
- PlayCanvas: drop 560px cap, use object-contain into available space,
  add fullViewport prop for chrome-less presentation rendering
- play page: F / Esc shortcuts + Fullscreen API + fullscreenchange
  sync; chrome-less black-letterbox overlay (bg-black) suited for
  screen recording
