Adds +47 to phone numbers in an uploaded CSV, preserves the source columns, and creates a reusable phone_international column for inspection and download.

A reusable CSV transformation model that adds a Norwegian country-code prefix to phone numbers. It creates an International Phone Numbers transform from contacts.csv, retains the name and phone columns, and adds phone_international with +47-prefixed values. The prefix can be changed to 0047 while updating the same transform. Reset removes generated results while preserving source assets, and a subsequent run restores the default +47 output.
