- Split single form into beneficiaryForm and transferDetailsForm
- Added MatStepper with custom icons and linear progression
- Added transfer status display with success/failure states
- Added missing i18n translation keys across all 13 locale files
- Fixed MatHint import for NG1010 compilation error
