Fallback to banner when response omits mediaType

detectMediaType returns undefined unless the exchange explicitly sets mediaType, and interpretResponse only copies the creative payload in the banner/video branches. If the endpoint returns a banner bid without mediaType (a common response shape), the adapter drops b.ad and emits a bid with no renderable creative, which can still pass required-key validation and then fail at render time when it wins.

Handle mixed banner/video requests without banner bias

The request builder hard-codes banner whenever both mediaTypes.banner and mediaTypes.video are present because the video branch is under else if. In multi-format ad units this silently strips video fields (playerSize, durations, video floor) and sends only a banner impression, so video demand is never requested for those placements.
