Subject: [PATCH] fix(gateway): align kanban artifact _IMAGE_EXTS with response
 dispatch

_deliver_kanban_artifacts used a broader _IMAGE_EXTS that included
.bmp, .tiff, and .svg. These three extensions are absent from the
equivalent set in _deliver_media_from_response (line 10661), which
intentionally routes them through send_document rather than
send_multiple_images (comment near line 10522 notes that Telegram
sendPhoto recompresses and rejects non-raster formats).

Routing .svg (XML text), .bmp, or .tiff through the photo API causes
send_multiple_images to raise on most platforms; the exception is caught
and logged as a warning, silently dropping the artifact. Aligning the
two sets ensures kanban deliverables with these extensions follow the
same send_document path as regular agent responses.

No behaviour change for .png/.jpg/.jpeg/.gif/.webp.
