Optimize Dockerfile: consolidate apt updates, add --no-install-recommends, clean caches

- Consolidate 3 apt-get update calls into 1 by adding all repos first
- Use apt-get instead of apt for non-interactive usage
- Add --no-install-recommends to all package installs
- Use dpkg --print-architecture for multi-arch Go download
- Clean npm/root caches and duplicate binaries in cleanup step
- Remove htop and python3-dev (not needed at runtime)
- Remove software-properties-common after PPA setup
