SMTP template now writes each accepted DATA body as a .eml file into a
bind-mounted per-decky quarantine dir and emits a `message_stored` log
with sha256, size, decoded headers, and an attachment manifest
(filename + sha256 + size + content-type). Attachment hashing uses the
*decoded* payload so operators can match against VT / MalwareBazaar
directly. Body accumulator is capped at SMTP_MAX_BODY_BYTES (default
10 MB, matching the EHLO SIZE advert) so a streaming client can't OOM
the container.
The existing /api/v1/artifacts/{decky}/{stored_as} endpoint now takes
an optional ?service= query param (defaults to ssh for back-compat)
and can serve .eml files out of the smtp subdir. Forensic metadata
rides the normal log pipeline, same as SSH file_captured.
