Implement improved UX with command transparency and log control

- Show exact Docker commands in parentheses for transparency
- Add log control: ask user if they want to see full Docker logs
- Clean, minimal output separation with refined ready message
- Browser opening option (default: Yes) with concise prompt
- Single-line wizard title combining instruction
- Removed excessive decorations and emoji for professional look
- Clear workflow: checks → selection → setup → ready
