Redesign onboarding with modern UI and subscription prompt

Complete overhaul of onboarding flow with 5 screens:
1. Welcome - Gradient intro with feature highlights
2. Time - Clean card-based time picker for reminders
3. Day - Tappable cards for today/yesterday selection
4. Style - Horizontal scrollable icon & color pickers
5. Subscription - Benefits list with free trial CTA

Design improvements:
- Beautiful gradient backgrounds on each screen
- Consistent typography and visual hierarchy
- White page indicators visible on all backgrounds
- Haptic feedback on selections
- "Maybe Later" option on subscription screen
