fix: improve text contrast for badges, category chips, and separators

- Change attraction category color from .yellow to orange variant for
  readable text in both light and dark mode (QuickAddItemSheet, POIDetailSheet)
- Fix "optional" badge to use textPrimary-based colors for strong contrast
- Bump paywall dashed separator from 0.4 to 0.6 opacity
- Fix SuggestedTripCard bullet separator from textMuted(0.5) to textSecondary
