## Description
The widget contact update endpoint (`PATCH /api/v1/widget/contact`)
applied updates that set an `identifier` without validating the
`identifier_hash`, unlike `set_user`, which already does. This change
runs the same validation on the update path whenever an `identifier` is
supplied, keeping identity validation consistent across the widget
contact endpoints.
Anonymous updates that don't pass an identifier (prechat
name/email/phone and custom attributes) keep working unchanged,
including on inboxes with mandatory identity validation.
