Add real-time TUI charts and sparklines (#10)

* Add real-time TUI charts and enhanced simulation

- Sparklines in main table showing throughput history
- Expandable detail view with full line charts (throughput/packets/errors)
- Sophisticated traffic simulation with realistic HPC patterns
- Ring buffer storage for historical metrics
- Auto-scaling units (GB/s, MB/s, KB/s)
- Keyboard navigation (j/k, Enter, Tab)
- Pulsing status indicators for active ports

* Fix formatting

* add totals to header, sparkline padding, bump to v1.0.0

* fix clippy lints in tests
