fix: add --surface-subtle token, restore info grouping, and apply theme-aware favorite color

- Add --surface-subtle (oklch 3% opacity) to replace rgba(0,0,0,0.03)
- Fix info items, creator-info, civitai-view, modal-send-btn, header-actions
  to use --surface-subtle instead of --surface-hover
- Keep true hover states on --surface-hover
- Use light #d4a017 / dark #ffc107 for --favorite-color based on theme
- Replace hardcoded #ffc107 and #d4a017 with var(--favorite-color)
