Remove 买点 (user acquisition tracking) subsystem

Delete the dataReport SDK, event storage model, and scheduled uploader,
along with the reportser/srv_report wrapper services and all ~20 Report*
call sites in business code. Also drop the ReportSDKConfig field from
the APP config response, the TrackerAppId helper, and the related
dataReport yaml config block.
