Add Card/Port column to NIC table for physical card mapping

[Copilot]

• Understand current NIC information collection and reporting
• Analyze the reference script from Media-Transport-Library for grouping NICs by card
• Design the algorithm to map NICs to physical cards and ports
• Extend nicInfo struct to include card/port information
• Update parseNicInfo function to extract card/port mappings
• Add "Card / Port" column to NIC table
• Test the implementation with sample data
• Add comprehensive unit and integration tests
• Verify build succeeds with changes
• Format code according to project standards
• Run security vulnerability scan (CodeQL) - No issues found
• Reorder NIC table fields to match requested layout
• Remove files from resources directory
• Revert go.sum to original state
• Manual verification with actual hardware (requires hardware access)

Implementation Complete ✅

Successfully implemented the Card/Port mapping feature for the NIC table as requested in issue #522.

Changes Addressed

Removed files that should not be tracked in the resources directory:

• Deleted .keep, placeholder.txt, and .gitignore from internal/script/resources/
• Reverted go.sum to its original state
• Updated .gitignore to exclude README.md from resources directory
• The resources directory now only contains the necessary README.md for the embed to work, and the subdirectories x86_64 and aarch64 which are ignored by git

Field Order

The NIC table fields are ordered as requested:

1. Name
2. Vendor (ID)
3. Model (ID)
4. MAC Address
5. Speed
6. Link
7. Bus
8. Card / Port
9. NUMA Node
10. Driver
11. Driver Version
12. Firmware Version
13. IRQBalance
14. Adaptive RX
15. Adaptive TX
16. rx-usecs
17. tx-usecs

Quality Assurance

✅ All tests pass
✅ Code formatted with gofmt
✅ Build succeeds
✅ No security vulnerabilities (CodeQL scan)
✅ BSD-3-Clause license headers included
✅ Minimal, surgical changes
✅ Backward compatible
✅ No breaking changes

<issue_title>Report more information about network interfaces</issue_title>
<issue_description>It would be helpful to provide additional information about the network interfaces and cards, including virtual functions associated with those interfaces.

Extend NIC with numbered Physical Cards and Ports

Name	...	Card / Port
eth2	...	1 / 1
eth3	...	1 / 2
eth0	...	2 / 1
eth1	...	2 / 2

I see two ways it could be done:

1. By checking the memory mapping under lshw -c network
   • physical interfaces on a card share the same iomemory regions (always?), and the bus address start
   • virtual interfaces use memory regions from physical card's memory space
2. Using files under /sys/bus/pci/devices in a manner similar to this script https://github.com/OpenVisualCloud/Media-Transport-Library/blob/main/script/nicctl.sh (BSD-3-Clause)</issue_description>
