Run Auctioneer in-process as a local auction provider #1511

Description

Link Auctioneer's bridge into the Trusted Server artifact and register it with the auction orchestrator as a local provider. A bidder that Auctioneer handles in-process is not also dispatched as a remote provider. This is the Trusted Server side of IABTechLab/auctioneer#76.

Done when

• The Trusted Server artifact for the selected deployment target links Auctioneer and serves auctions with it as a local provider.
• No bidder is dispatched twice, once locally and once remotely.
• Consent, identity, and privacy behavior is unchanged or explicitly specified, with tests.

Affected area
