Speed up the app, run production build, remove chunk ink, start App.jsx split

Performance:
- Lazy-load pages, docx, and mammoth (initial JS 1,298 KB -> ~290 KB)
- Gzip responses and cache hashed assets for a year
- Memoize DrawCanvas strokes so ink isn't redrawn on every render
- Precompute whole-Bible search index and defer the query while typing
- Reload once if a lazy chunk is missing after a deploy

Deployment:
- setup.sh builds and runs one production server on APP_PORT (default
  5173); --dev keeps the old Vite dev setup
- Session cookie uses secure: 'auto' so login works behind any proxy

Chunk editor:
- Remove the Draw layout, Ink Notes panel, and ink in HTML export
  (existing inkStrokes data is left in saved projects)

Refactor:
- Move module-level helpers out of App.jsx into src/utils/*
- Extract Bible reader state and logic into hooks/useBibleReader
