fix(repair): remove default timeout from RepairStatus

Since StorageServiceRepairStatus (without timeout param) returns only when the repair job has finished, we shouldn't time out on our end (even if backoff retry could handle that).

This resulted in many backoff errors in SM logs even on successful repair:
{"L":"INFO","T":"2023-12-01T01:31:54.398Z","N":"cluster.client","M":"HTTP retry backoff","operation":"StorageServiceRepairStatus","wait":"28.607063257s","error":"after 16m0s: context deadline exceeded","_trace_id":"uqSjtDSfRoOl1WhetiLPgA"}
