fix(docker): add \$PNPM_HOME/bin to PATH in custom Dockerfiles (#47)

Upstream fixed this in Dockerfile.admin/web/space/live via makeplane#9079 but our
custom Dockerfile.iw-* variants weren't included in that merge. Same fix:
  ENV PATH="\$PNPM_HOME:\$PNPM_HOME/bin:\$PATH"
Without /bin, corepack-installed pnpm binaries aren't resolvable and
pnpm add -g turbo fails with "global bin directory not in PATH".
