fix: preserve wood paneling on dashboard refresh and improve colors

- Fix View All link flashing by preserving data-wood attribute when dashboard re-renders
- Update wood-dark text color to match wood-mahogany (#f5f5f5) for better consistency
- Add smart link colors for wood paneling (#0066cc for light wood, #66ccff for dark woods)
- Fix carousel arrow gradients to be less harsh on wood backgrounds (0.6 for light, 0.3 for dark)
- Remove accent color preservation rule that was conflicting with wood-specific link colors
