sharps: _open_split folds by the data-api redeemable flag, not price-pinning

Audit of the two biggest All-Time-vs-PM divergences (oliman2, leegunner)
proved the fold-in RIGHT and PM's leaderboard wrong: live per-position
sums reproduce our numbers to the dollar (oliman2 +181,594 closed
-160,644 abandoned = ~+19k true vs leaderboard 112k; leegunner +323,707
-58,762 = ~274k true vs 347k). redeemable is exact (set on resolution
for winners AND losers); pinning misfolded a few unresolved longshots.
