fix: preserve contact methods and notes in export/import workflow

- Fix contactMethods not being exported (was checking for string instead of array)
- Add missing notes and iViewContent fields to $insertContact method
- Normalize empty strings to null when saving contacts in ContactEditView

This ensures contact data integrity is maintained during export/import operations.
