Split requests by media type before choosing endpoint

buildRequests picks the endpoint from only the first bid (validBidRequests[0]) but still converts and submits the full validBidRequests array in one ORTB payload. In auctions that include both Taboola banner and native ad units, this sends one media type to the wrong host (display... or native...), which can drop bids for whichever type doesn’t match the chosen URL.

Useful? React with 👍 / 👎.

Preserve ORTB mtype when decoding mixed-format responses

The response converter unconditionally sets context.mediaType from the original bid request, and getMediaType resolves mixed banner+native requests to banner. That overrides the default ORTB media-type detection from bid.mtype, so native bids returned for mixed-format requests are interpreted as banner (missing native.ortb and getting banner ad handling instead).

Useful? React with 👍 / 👎.

@ronishefi9 this seems like a significant issue, much of your native demand will be multiformat
