Create dedicated network collector with physical/virtual interface grouping

Move network collection from NixOS collector to dedicated NetworkCollector. Add link status detection for physical interfaces (up/down). Group interfaces by physical/virtual, show status icons for physical NICs only. Down interfaces show as Inactive instead of Critical.

Version bump to 0.1.165
