The current flash configurations for all nRF52840's in Zephyr is VERY constrained when it comes to allowing samples any space for storage or custom areas. It only leaves the last 4 pages of flash for "storage". The nRF52840 is also capable of using OpenThread which defaults to using the last 4 pages of flash for storing OpenThread-related network data. This means that while using OpenThread under any configuration designed to use mcuboot partition slots, there is no space left over for storage of any kind. Let's adjust the partition table to set storage at 8 pages of flash (32k). This fixes the conflict with OpenThread and leaves room for future use cases that may arise.
