ci: cache turbo, npx and Metro; install web deps before copying code

- ci-ts restores the local turbo cache, so unchanged packages skip
  typecheck, test and build
- ci-mobile caches the npx copy of expo-doctor and Metro's transform cache
- the web image copies only workspace manifests before pnpm install, so the
  dependency layer survives code changes (CI docker job and update.sh)
- docs: table of what is cached where
