Add PWA support and expandable draw canvas

Browse Source

PWA:
- manifest.json with name, icons, theme/background color, standalone display
- PNG icons (192, 512, 180 apple-touch) generated via pure Node.js (no deps)
- index.html: manifest link, theme-color, apple-mobile-web-app-* meta tags,
  viewport-fit=cover for iPhone notch/Dynamic Island
- service worker extended to cache app shell (static assets + index.html)
  with network-first for navigation, cache-first for hashed assets,
  network-first-with-cache-fallback for external Bible APIs

Expandable canvas:
- "Add More Space" button below each draw canvas adds a full notebook page
- Existing ink rescales to preserve visual pixel positions (no stretching)
- Page count embedded as metadata in the strokes array so it survives
  navigation without a separate state key
