"""POST /api/contacts/import must not 500 on a non-string vcf/text/csv value.

`text = data.get("vcf") or ... or ""` left a non-string value (e.g. a number)
in place, so the next `text.strip()` raised AttributeError -> HTTP 500. The
handler now coerces with str() and degrades to a structured "no data" response.
