release v4.12.0-fazer-ai.44 (#253)

* fix(whatsapp): use payload filename for documents to avoid Content-Disposition parsing issues

When receiving documents via the WhatsApp Cloud API, filenames with
spaces or special characters were mangled due to the Down gem's
case-sensitive Content-Disposition header parsing. Now uses the
filename from the WhatsApp message payload when available, falling
back to Content-Disposition for other attachment types.

* fix: scope payload filename preference to document messages only

* fix: revert document-only scope, apply payload filename for all attachment types
