…build

- Add -bookworm suffix to Debian-based Dockerfile templates to ensure
  consistent base images (postgres-14, postgres-15, postgres-16,
  postgres-17, postgres-18, latest)
- Update Alpine template to use versioned LLVM packages (llvm19-dev,
  clang19, llvm19-libs) instead of generic clang/llvm
- Refactor Alpine build commands for better readability
