Replace the legacy points-to-balance and external points purchase flows with direct integer balance-to-points exchange. Enforce exchange and points-transfer limits and capability checks across the UI and REST API.
Apply the configured order lifetime to all checkout flows and close unpaid orders once their expiry is reached.
Move all domain folders from src/AKSRT/{Domain} to src/{Domain}; remap Composer PSR-4 "AKSRT\\": "src/"; update audit script + README + ADR paths; remove dead tools/build-psr4-map.php (scanned deleted inc/classes).
