Flag and charge past-due cycles

POST/api/v1/credit/cycles/assess-late

Flags past-due cycles and charges them under each program's configured late rule — rate basis, grace period, day count, compounding, and cap. A program with no late rule still gets the status flag but is not charged, since the rate basis would have to be invented. Idempotent per cycle per day, so re-running the sweep never double-charges. Pass dry_run to preview.
