fix: remove dark: variants, use theme colors only

ISSUE: Tailwind v4 doesn't handle dark: variants the same way as v3
The dark: prefix wasn't working properly in light mode

SOLUTION: Replace all dark: variants with theme-aware colors

Admin Pages:
- AdminPlans: badges use bg-primary/20, bg-green-500/20, etc.
- AdminUsers: role/status badges use opacity-based colors
- AdminDashboard: stat cards use /20 opacity backgrounds

Member Pages:
- Overview: chart tooltips use text-foreground

Benefits:
✅ Works correctly in both light and dark mode
✅ Colors automatically adapt via CSS variables
✅ No more hardcoded dark: classes
✅ Consistent opacity-based approach

Technical:
- Tailwind v4 uses @theme and CSS variables
- dark: variants need proper configuration
- Using /20 opacity on colors works universally
