Send Envelope for Signing

Send an envelope to all recipients for signing. Normally transitions the envelope from `draft` to `pending`. When `workflow.estampEnabled` is true, returns `202`, transitions to `estamping`, and queues the provider e-stamp step; recipients are notified automatically after the stamped PDF is ready. No request body is needed. Workflow settings are configured during envelope creation via `POST /envelopes`. Requirements: - At least one signer or approver recipient - PDF file must be uploaded - Sufficient credits - A complete `estampConfig` when e-stamping is enabled
