Startup roundtrip now verifies persistence accounting inline:
- Wires PinkClickHousePersistence to a mock sink after EXIT
- Checks trade_events: exit_price != entry_price, pnl finite, capital finite
- Checks trade_exit_legs: pnl_leg, exit_qty, exit_price all populated
- Logs ALL FIELDS CORRECT / ISSUES DETECTED
Flatness check scoped to PINK's traded asset only (other strategies
may have open positions; those are reported informational, not failure).
Adds _normalize_asset() for TRX-USDT → TRXUSDT symbol normalization.
