fix(jenkins): scope multi-branch build collection to current project (#8430) (#8781)

The branch jobs query in collectMultiBranchJobApiBuilds selected all
WorkflowJob entries across all multi-branch pipelines for a connection,
causing builds to be duplicated and misattributed. Filter by
_raw_data_params to collect only the current project's branch jobs.
