feat(oneshot): add auto-redemption via RedeemEngine

Browse Source 
When a position's market expires, RedeemEngine automatically polls the
CTF contract and redeems the winning position on-chain — no manual redeem needed.

Flow:
  1. expirePosition() queues the expired position into RedeemEngine
  2. RedeemEngine polls every 30s (ONESHOT_REDEEM_POLL_MS)
  3. Checks Gamma API first, then CTF.payoutDenominator() on-chain
  4. When settled: emits redemption:complete event with final P&L
  5. Orchestrator passes P&L to RiskEngine

DRY_RUN=true: simulates by reading on-chain payouts and logging win/loss
DRY_RUN=false: submits real redeemPositions() tx on Polygon (gasLimit 300k)

Also stores conditionId and negRisk in PositionEngine state so the
expired position has all data needed for redemption without extra lookups.
