P&L: fold abandoned losers into realized (anti-survivorship) — All-Time is the truth, not PM

Resolved-but-unredeemed positions (bets that lost, went to $0, never
redeemed) were sitting in Open P&L, breaking the All-Time+Open=PM reconcile
and — worse — hiding real losses. _open_split now routes decided positions
(curPrice pinned 0/1) into the REALIZED total at their outcome, leaving only
genuinely in-flight positions in Open P&L. This is the project's founding
survivorship insight applied to P&L: PM /profit under-counts abandoned
losers unevenly, so where our All-Time reads lower than PM, PM is biased and
ours is honest. oliman2 $181k->$20k (walked from $161k of losers),
JuiceFarm $380k->$32k; clean wallets unchanged (ewww1 $409k, KBO30 ~PM).
Win% now counts abandoned losers too. Verified: Coteykens/imwalkinghere/KBO30
now ~PM; oliman2/JuiceFarm correctly far below their flattering PM.

+11. **All-Time / Conv P&L is the wallet's ANTI-SURVIVORSHIP realized track
+    record.** Every DECIDED position at its actual result: redeemed/sold closed
+    positions (Polymarket's own `realizedPnl`, `cache.closed_exits`) PLUS
+    resolved-but-unredeemed positions still sitting in `/positions` — bets that
+    already won/lost and the wallet never redeemed (mostly **abandoned losers**
+    at $0). `_open_split` in validate_timing pulls current positions and routes
+    those decided ones into the realized total (`cashPnl` = their outcome),
+    leaving only genuinely in-flight positions in the **Open P&L** column. This
+    is the whole point of the project surfacing: PM `/profit` **under-counts
+    abandoned losers**, unevenly — Coteykens' PM subtracts them (realized $66k −
+    $52k walked-away = $14k = PM), oliman2's does not ($181k − $161k = $20k
+    true, yet PM says $112k). So where our All-Time reads **lower** than PM, PM
+    is the survivorship-biased number and **ours is the truth** (oliman2 and
+    JuiceFarm look elite on redeemed-only P&L, ~$20k/$32k once the losers they
+    walked from are counted). This *replaced* the old hold-to-resolution
+    reconstruction (`won × entry × size`), which diverged by up to 10× and
+    flipped signs — four bugs killed with it: the 2,000-row pull cap, both-sides
+    double-drop, `initialValue = 0` mis-sizing, and corrupt near-epoch `res_t`.
