feat(standard-seasons): enable secret mode (60min) and improve autumn theme colors

- Enable secret mode with 60 minute offset (1 hour) by default in all season demo data
- Improve autumn theme color contrast for better text visibility
  - Lower background from #fcf9f2 → #faf5f0 for more contrast
  - Darken primary from #a93529 → #8b2e1f for better visibility
  - Adjust secondary, accent, and text colors for better readability
  - Update card background and border colors
- Fixes issue where autumn theme text was too light and hard to read in month/week views
- Ensures seasonal themes have consistent design quality
