fix: properly parse ip addr show output for network interfaces

[kennethdsheridan]

Summary

Fix the network interface parser that was returning placeholder data (eth0 with 192.168.1.100) instead of actual interface information.

Problem

The parse_ip_output() function in src/domain/parsers/network.rs was a stub implementation that always returned the same dummy data regardless of the actual ip addr show output. This prevented proper detection of:

• Real interface names
• Actual IP addresses
• Tailscale VPN interfaces
• MAC addresses

Solution

Properly parse the ip addr show output:

• Parse interface names from X: ifname: lines
• Extract MAC addresses from link/ether lines
• Handle Tailscale tunnel interfaces with link/none
• Parse IPv4 addresses from inet lines
• Classify interface types (tailscale, wireless, bridge, ethernet)

Testing

• cargo check passes
• This enables proper Tailscale IP detection for NetBox network_access_ip field
