refactor: Unify section headers and simplify variable display

- Unified handling of required variables across all sections
- Section headers now always show: 'Icon SectionName' (no more 'Required Configuration')
- Icons appear only with section headers, not in value displays
- Optional values shown inline without headers (just the values)
- Consistent formatting whether section has enabler, required vars, or only optional
- Cleaner, more concise output with better visual hierarchy

Example:
📦 General
Enter service_name: ...
container_name: nginx, port: 8080
Do you want to change any values?
