refactor: 管线写入依赖解耦——pipeline_write 直接 import

bzzoiro_events / bzzoiro_standings / bzzoiro_stats 直接 import
src.data.pipeline_write(_write_raw_event/_write_lineage/_safe_write_ingest_failure),
删除 bzzoiro.py 门面中的 pipeline_write 转发胶水。

保留 fetch_*/_fetch_json_async/REQUEST_INTERVAL 经 bz. 门面调用(测试 monkeypatch 入口);
测试 best-effort 改为 patch 管线模块自身命名空间(from-import 绑定语义)。
函数语义与「失败不拖垮主流程」不变;source_record_id/transform_name 约定不变。

全量测试 270 通过。
