docs/reference/837p.md line 48: the CO Medicaid trading-partner line
was still saying 'SKCO0 (sender) <-> COHCPF (receiver)'. The HCPF
837P Companion Guide (June 2025 - Version 2.5) requires
NM1*PR NM109 = CO_TXIX; SKCO0 causes Gainwell to reject the SET
('2010BB NM109 must equal CO_TXIX or CO_BHA').
docs/reference/co-medicaid.md line 118 + the Trading Partner table at
the top: same fix, with a pointer to the SP33 spec for the
root-cause story.
No code changes. Pure doc fix to match what the source now emits
(PayerConfig.co_medicaid().payer_id = 'CO_TXIX').
