Add responsive column visibility to service panel

Service panel now dynamically shows/hides columns based on terminal width:
- ≥80 chars: All columns (Name, Status, RAM, Uptime, Restarts)
- ≥60 chars: Hide Restarts only
- ≥45 chars: Hide Uptime and Restarts
- <45 chars: Minimal (Name and Status only)

Improves dashboard usability on smaller terminal sizes.
