Lower merge-tree free-entry thresholds for small background pools, bind listen_host to 0.0.0.0 for published ports, and allow CLICKHOUSE_ENABLED=true in tests for live_ch smoke coverage.

Tuned for small control-plane hosts (e.g. 3c6g).
|
|
|
|
background_pool_size * background_merges_mutations_concurrency_ratio must stay
|
|
greater than merge_tree number_of_free_entries_in_pool_to_execute_mutation
|
|
(ClickHouse 25.x refuses to start otherwise). Keep the merge free-entry
|
|
thresholds low so a small pool remains valid.
