style: Replace hardcoded #fff colors with theme.white in program/whats-new components

[claude]

Description

Several components use hardcoded #fff color values instead of the semantic theme.white from ThemeContext. This violates the theming guidelines in CLAUDE.md which states:

Use semantic colors from ThemeContext, never raw Palette colors

Files Affected

1. components/program/DayDetailSheet.tsx

   • Line 66:
   • Line 173: color: '#fff' in styles

2. components/program/LogMeetingSheet.tsx

   • Line 246: color="#fff"
   • Line 489: color: '#fff'

3. components/program/MeetingsCalendar.tsx

   • Line 221: color: '#fff'

4. components/whats-new/WhatsNewVersionSection.tsx

   • Line 223: color: '#ffffff'
   • Line 235: color: '#ffffff'

5. components/whats-new/WhatsNewFeatureCard.tsx

   • Line 35: Hardcoded skeleton background color
   • Lines 51, 58: TYPE_CONFIG with hardcoded green/purple colors

Recommended Fix

Replace all #fff / #ffffff with theme.white using the theme from useTheme() hook.

For WhatsNewFeatureCard TYPE_CONFIG, consider:

1. Moving type colors to the theme system, or
2. Creating semantic constants if these are intentionally fixed brand colors

Priority

Low - cosmetic consistency issue, no functional impact
