Prefer retryable banner when retries are still enabled

In partial-submission runs, run_strategy_cycle can set funding_blocked=True while still setting execution_block_retryable=True (because only terminal funding blocks disable retries), but this branch always chooses funding_blocked_banner first and tells users there will be no more automatic retries. That produces incorrect operator guidance for PARTIAL_SUBMITTED runs where the scheduler should still retry within the window.
