feat(cli): remove ALL ugly boxes from status output - now fully beautiful

Removed the last remaining ugly ASCII boxes:
- Version info box (┌─┐│└┘) that appeared at top
- Async version check box that ended randomly in middle
- Configuration error box

Now status output is 100% clean and beautiful with just colored text:

● Service: active (running)
  PID: 9120  Memory: 45.7M  CPU: 190ms

UPS Devices (2):
  ⚠ Test UPS (SNMP v1) - On Battery
    Battery: 100% ✓  Runtime: 48 min
    Host: 192.168.187.140:161

  ◯ Test UPS (SNMP v3) - Unknown
    Battery: 0% ⚠  Runtime: 0 min
    Host: 192.168.187.140:161

No boxes, just beautiful colored output with symbols!
Bumped to v4.1.0 to mark completion of beautiful CLI feature.
