Route carousel media by URL type to avoid double-downloading videos

Browse Source 
Carousels return a mixed image+video URL list. The uploader keyed on the
post's media_type, so every carousel URL went through the image optimizer;
videos failed PIL ('cannot identify image file') and were then re-downloaded
for the raw fallback. That double download per video pushed the synchronous
scrape past the backend's request timeout, so the backend imported 0 while
the engine still saved posts to its own DB (causing a dedup desync on retry).
Detect video URLs up front and send them straight to the video uploader.
