Fix dependency handling in preflight and setup scripts

- Changed required packages to warnings in preflight.sh (setup.sh installs them)
- Modified setup.sh to proceed with warnings from preflight checks
- Ensures Docker installation installs all dependencies automatically
- Preflight no longer fails on missing jq, tmux, etc.
