test(webapp): rewire dangling-connected-runs to the run store and stabilise flaky tests

- waitpointPresenter.danglingConnectedRuns: inject a container-backed run store
  (the connected-runs read moved onto the run store), matching its siblings.
- apiRetrieveRunPresenter readroute + groupedLockedWorker: use postgresTest
  instead of containerTest (Postgres-only) to stop the 10s fixture timeout; the
  N+1 regression coverage is unchanged.
- runsReplicationService part9: replace the live lag-histogram label poll with a
  deterministic metric read/merge test.
- runsReplicationInstance: poll both leader-lock keys for readiness instead of a
  fixed 3s sleep.
