feat(market): host and publish the cover photo with each offer
Wire the Blossom MediaTransport into publishing: shareable lots carry their varietyId, publishLots uploads the lot's cover photo and puts the returned URL on the offer (best-effort — a hosting failure still publishes the offer, just without a photo). Add a configurable media server (Comunes default, empty to opt out) to settings and the market advanced config.
