Refactor: apply PhoneInputCustom to PortofolioEdit

Changes:
- Replace react-native-international-phone-number with PhoneInputCustom
- Remove ICountry dependency, use CountryData from constants
- Add phone number state management
- Implement country detection from existing phone number
- Auto-detect country based on calling code on load
- Improve phone number formatting logic

Features Applied:
✅ NO emoji flags - only calling codes (+62, +65, etc)
✅ Clean, professional UI
✅ Modal country picker with search
✅ Auto-detect country from saved phone number
✅ Real-time phone number formatting
✅ Auto-update country code on change
✅ Consistent with LoginView & ScreenPortofolioCreate

Phone Detection Logic:
- Load existing phone number from API
- Detect country by matching calling code
- Extract phone number without country code for display
- Set detected country for country picker
- Re-format on country change

UI:
- Phone Input: [+62 ⌄ | xxx-xxx-xxx]
- Country Picker: Modal with search
- Display: Country name + calling code only
