fix: Resolve TSCM function strip visibility and clipping issues

- Fix function strip content being clipped by changing overflow to visible
- Add min-height and increased padding to function strip
- Add explicit colors for TSCM strip stat values and labels
- Fix output-panel overflow for TSCM mode using :has() selector
- Add CSS variables --bg-dark and --bg-panel aliases
- Clean up sidebar section margins for consistent spacing
- Add unique IDs to WiFi/Bluetooth export sections for restore function
