    branch-4.1: [fix](test) stabilize remaining 
Cloud-P0/P0/NonConcurrent/External flaky cases (test-only backport rest of 
#64525) (#64613)
    
    ## What problem does this PR solve?
    
    Back-ports the **remaining test-only** subset of branch-4.0 #64525 to
    branch-4.1,
    covering the cases still flaky/red across branch-4.1 **Cloud-P0 / P0 /
    NonConcurrent /
    External** pipelines (the first three subsets are #64597, #64603,
    #64607). All changes
    are under `regression-test/` — **no FE/BE code, no compile impact**.
    
    Cases addressed (and where they fail today on branch-4.1):
    - **query64** (`shape_check.tpcds_sf100/sf1000 .../query64`) — currently
    an **un-muted P0 red**; #64525 `ignore`s it.
    - **test_colocate_join_of_column_order** — muted on Cloud-P0.
    - **test_audit_log_behavior** — muted on NonConcurrent (query_id width).
    - **test_routine_load_adaptive_param** + `RoutineLoadTestUtils` — muted
    on NonConcurrent/P0 (timeout convergence / drive-data deflakes).
    - **parse_sql_from_sql_cache** (drop racy cross-FE assertNoCache),
    **test_sql_block_rule_status** (single-FE read) — muted on P0.
    - **test_file_cache_statistics** (sum across cache paths),
    **test_hive_ctas_to_doris** — muted on External.
    - **test_variant_compaction_with_sparse_limit** (pin
    `default_variant_max_subcolumns_count` so the session-var fuzzer can't
    shrink it), **check_before_quit** (pin variant session defaults) —
    variant deflakes.
    - **partition_curd_union_rewrite** (guard mv-chosen with
    partition-stats-ready), **test_f_delete_publish_skip_read** (wait for
    delete visibility), backup/restore `restore_reset_index_id`
    serialization.
    
    ## Deliberately NOT included
    - `[fix](compaction) time_series_level2_file_count debug point` —
    touches BE (`cumulative_compaction_time_series_policy.cpp`), needs a
    manual port (`olap`→`storage` on 4.1) + remote compile; separate PR.
    - `[fix](test) deflake AutoProfileTest` — an FE UT
    (`fe/fe-core/src/test/.../AutoProfileTest.java`), separate FE-UT
    pipeline; out of scope for this regression-test PR.
    - `skip test_parquet_join_runtime_filter` — its stated reason is
    **4.0-specific** ("4.0 does not support this feature"); the feature
    exists on 4.1 and the test passes there, so skipping it on 4.1 would be
    wrong.
