Code Quality Improvements

Fixed Deprecation Warnings

Issue: shadow*" style props are deprecated. Use "boxShadow"

Fix:

// BEFORE
shadowColor: '#000',
shadowOffset: { width: 0, height: 2 },
shadowOpacity: 0.05,
shadowRadius: 4,

// AFTER
boxShadow: '0 2px 4px rgba(0, 0, 0, 0.05)',

Files Fixed:

• SettingsScreen.tsx

Fixed React Native Web Compatibility

Issue: Alert.alert() with button arrays doesn't work properly on React Native Web

Fix:

• Created FontSizeModal.tsx to replace Alert-based font size selector
• Simplified biometric toggle to avoid button arrays
• Now all interactive elements use proper modals or simple alerts

Files Fixed:

• SettingsScreen.tsx - Replaced Alert.alert() with modal
• FontSizeModal.tsx - NEW professional font size selector

Fixed TypeScript Errors

Issue: TermsOfServiceModal and PrivacyPolicyModal don't accept onAccept prop

Fix:

• Removed onAccept prop from modal calls in SettingsScreen
• Modals now only use visible and onClose props

Files Fixed:

• SettingsScreen.tsx
