fix(robomp): promote deferred events on periodic sweep

Ran deferred-submission promotion on an independent timer in addition to the empty-queue path, so a sustained ordinary queue can no longer starve a rate-limited submitter after their rolling window frees. Added ROBOMP_DEFERRED_PROMOTION_SCAN_SECONDS to tune or disable the sweep. Fixes #5882
