Record dispatch immediately before the provider call

Moves a claimed presentation attempt to dispatching. After this, lease expiry cannot reassign the attempt; a lost provider response settles as indeterminate rather than a blind retry.

Checkfu support posture: alpha; hosted. Required evidence journey: collaboration-identity. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
