Add AER decode, event counter, and sparkline to component detail modal

- decodeAERStatus: parses aer_status hex from kernel error strings and
  maps PCIe AER register bits to human-readable names with correctable/
  uncorrectable classification (e.g. "Receiver Error, Replay Timer Timeout (correctable)")
- renderSparkline: 100px inline SVG showing non-OK events over time,
  bars positioned proportionally to timestamp; evenly spaced when timestamps coincide
- renderComponentDetail: shows event count badge and sparkline in the
  component header row; decoded AER line appears below the raw error summary
