standardize design to s/w standard - fix non-standard color usage

- replace hardcoded green/red/blue colors with standard shadcn semantic colors
- use text-primary, text-secondary-foreground, text-muted-foreground instead of text-green-600/blue-600
- replace colored backgrounds with bg-secondary, bg-muted, bg-primary/5
- maintain proper contrast and accessibility with semantic color tokens
- ensure consistent black/white theme across all components
