Update payment link status

Change the status of a payment link. Active links accept payments, inactive links are temporarily disabled, and archived links are permanently disabled and cannot be reactivated. --- **Related endpoints** - `POST /payment-links` — Create a new payment link - `GET /payment-links` — List payment links - `GET /payment-links/{id}` — Get payment link by ID - `POST /payment-links/{id}/expire` — Expire a payment link (deprecated) - `POST /payment-links/{id}/deactivate` — Deactivate a payment link (deprecated) - `POST /payment-links/{id}/activate` — Activate a payment link (deprecated) - `POST /payment-links/{id}/archive` — Archive a payment link (deprecated) **Common errors** - `400 invalid_request` — malformed payload or failed validation. - `401 authentication_error` — missing, invalid, expired, or revoked credential.
