fix(run-ops split): wire batch-results route with split read-through deps

The api.v1.batches.$batchParam.results route constructed ApiBatchResultsPresenter
with no read-through deps, collapsing call() to a passthrough read off the
control-plane replica only. A NEW-resident (ksuid) batch on the dedicated run-ops
DB was invisible to that read and the route returned 404. Wire the presenter with
splitEnabled + newClient + legacyReplica, mirroring the batch-list and waitpoint
token read routes.
