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0 (equivalent to money_only on current data, diff 0 rows) and correct the withdrawn 407-row/17.2% wording in cpa_caliber docstring.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).
