feat: Add compact optional configuration display with icons

- Removed 'Optional Configuration' header
- Display as single line with category icon
- Format: '📦 General: var1: value1, var2: value2'
- Icons for different categories (network, traefik, swarm, etc.)
- More concise and visually appealing output
