Fix Settings screen React Native Web compatibility

Issues Fixed:
1. Alert.alert() with button arrays doesn't work on React Native Web
   - Created FontSizeModal to replace Alert-based font size selector
   - Simplified biometric toggle to avoid confirmation dialog with buttons

2. TypeScript errors with modal props
   - Removed invalid onAccept prop from TermsOfServiceModal and PrivacyPolicyModal calls

3. Web compatibility improvements
   - All interactive elements now use proper modals or simple alerts
   - Font size selection shows professional modal with preview
   - Biometric auth directly prompts for authentication

Files Changed:
- src/screens/SettingsScreen.tsx: Fixed Alert.alert() usage, added FontSizeModal
- src/components/FontSizeModal.tsx: NEW - Professional font size selector
- PHASE_1_COMPLETE.md: Updated documentation with fixes
