v1.5.4

Includes the popup authentication and closed-store recovery improvements from 1.5.3, using only the existing WooCommerce Consumer Key and Consumer Secret.

Production completion checks now follow every accepted popup cycle, including after a store reopens or popup mode is disabled. Completed batches stop polling. Checks use the existing hourly schedule and WooCommerce credentials.

Requires the updated Rumble wc-rumble/v1 endpoint. Verified credential permissions, complete order counts, retry idempotence, archived-cycle protection, and completion tracking across reopenings.
