Jira issue: CRDB-67208

Start by running kv/kvserver.TestPrepareSplitManifestsDataDriven/pebble/split_manifest with the reported race configuration and read pkg/kv/kvserver/client_split_manifest_test.go. Trace the failure through installTestManifestForKey in client_basalt_manifest_helpers_test.go and the reported storage call sites. Done means the test no longer fails under the reported basalt configuration.
