Fix setup.sh to install system tools before Python deps

- Reorder: check tools -> install tools -> Python deps
- This ensures system tools install even if pip fails
- Make pip failures non-fatal (continue with warning)
- Auto-install python3-venv if needed on Debian
- Don't exit on venv creation failure, continue with tools

The previous order meant if pip failed (common on fresh installs),
the script would exit before installing rtl-sdr, multimon-ng, etc.
