Fix EOD exit: sweep DB for stale pending candidates after restart; remove misleading compound_returns override

- run_eod_exit now queries DB for any pending candidates not in-memory
  (guards against server restart mid-day leaving zombie pending records)
- Remove compound_returns=True force-override; live engine doesn't use it
  and V23 config has compound_returns=false
