ci/woodpecker/push/main Pipeline failed
fix(cpa): sales bill-type whitelist for customer revenue caliber (P0)
Customer revenue/concentration now filters bill_type IN (1,4,14) (XSD/XSTHD/XSHHD).

Non-sales docs (JHD purchase, YFKD prepay, YSKD accept, QTRK, SKD, YBFYD) carry SUPPLIER unit_id and were polluting 'customer concentration' (old Top1/Top2 were our biggest suppliers; root cause of 6.04x base gap).

Unify sign filter to (sum_money+sum_tax_money)>0 (equivalent to money_only on current data, diff 0 rows) and correct the withdrawn 407-row/17.2% wording in cpa_caliber docstring.

Deriver: anchors from cpa_caliber single source; new --concentration overwrite and --only concentration (minimal 9-row write face) with pre-overwrite backup.

Tests: fixture gains bill_type/sum_tax_money; +5 whitelist cases (44 passed targeted).

2) `kpi_values` 汇总口径(**只存汇总,避免 284 客户 × 期数污染 KPI 宽表**,任务 §2.1):
* `C_CUST_REVENUE` 期内客户收入合计(万元)
* `C_CUST_COUNT` 期内活跃客户数(个)
* `C_CUST_CONCENTRATION` 现网定义 = 前5大客户收入 ÷ 期内合计 ×100。
`--concentration`(默认 `fill-gaps`)控制**已有期次**的处置:
* `fill-gaps` = 仅补库内尚无该期行的期次(2026-01~09 九期原样保留)
* `overwrite` = **重算并覆盖**指定期次(P0 口径纠错后重算九期用;
属生产写,须走放行)
