chore: upgrade react-native-modal-datetime-picker from 14.x to 18.x

[hb2708]

Summary

Upgrade react-native-modal-datetime-picker from 14.0.1 to 18.x. The package is several major versions behind and likely has breaking changes to its component props and event handlers.

Current → Target

Package	Current	Latest
react-native-modal-datetime-picker	14.0.1	18.0.0

Why Upgrade

• Multiple major versions behind — likely missing bug fixes and platform improvements
• Better compatibility with latest @react-native-community/datetimepicker (currently at 8.6.0)
• Improved dark mode and accessibility support

Migration Steps

1. Install new version:

   yarn add react-native-modal-datetime-picker@latest

2. Review changelog for each major version bump (15, 16, 17, 18) — check for:
   • Renamed or removed props
   • Changed callback signatures (e.g., onConfirm, onCancel)
   • New required props
3. Search codebase for all usages:

   grep -r "react-native-modal-datetime-picker" app/ --include='*.ts' --include='*.tsx'
   grep -r "DateTimePickerModal" app/ --include='*.ts' --include='*.tsx'

4. Test on both platforms — date/time pickers behave differently on iOS vs Android
5. Run yarn ci to verify

Files Likely Affected

• Any screen/component using DateTimePickerModal
• Likely in emission entry forms or date selection screens
