Andrey Vasnetsov c4a22aa124 Add timeout to streaming shard snapshot writer (#9239) ...

* Add block level timeout to snapshot stream writer

* Add tooling to exercise streaming snapshot stalls

- tests/manual/slow_snapshot_download.py: slowly / partially download a
  streaming shard snapshot from a URL to exercise sender-side backpressure.
  Supports hold / rst / fin / blackhole termination to simulate a stalled,
  killed, or offline (network-partitioned) consumer against a remote node.
  Stdlib only; read-only against the target.
- tests/consensus_tests/test_streaming_snapshot_receiver_kill.py: throttled
  receiver killed mid-flight + a second receiver, to observe whether the
  sender releases the SegmentHolder lock and recovers.
