Import Contacts From a CSV File: Code Review Practice

Adds an Import button to the Contacts page. Upload a CSV with name, email, and phone columns, and the importer creates a contact for each row. Rows with an email you already have are skipped, so importing the same file twice doesn't duplicate anyone. Tested with a sample export.
