feat: add min/max temperature tracking for nodes

Browse Source 
Track minimum and maximum CPU temperatures since monitoring started.
This provides better insight into temperature trends and cooling
adequacy over time.

Changes:
- Backend: Add CPUMin, CPUMaxRecord, MinRecorded, MaxRecorded fields
  to Temperature model
- Backend: Implement min/max tracking logic in monitoring cycle that
  preserves values across polling cycles
- Backend: Initialize min/max on first reading, update on extremes
- Frontend: Update Temperature TypeScript interface with new fields
- Frontend: Display min/max range in NodeCard tooltip (e.g., "52°C
  (48-67°C since monitoring started)")
- Frontend: Rebuild dist assets

Temperature display now shows:
- Current temperature with color coding (green/yellow/red)
- Tooltip with full min-max range and context
- Min/max tracked in-memory (resets on Pulse restart)

Example tooltip: "CPU: 52°C (48-67°C since monitoring started)"
