The swapped_app image, added via ExternalZephyrProject_Add, wasn't receiving the swap method configuration from sysbuild. If trying to build the test with a different configuration that SWAP_USING_OFFSET (for example SWAP_USING_MOVE) this resulted in a boot loop due to configuration mismatch between swapped_image and mcuboot.
This fix ensures proper configuration propagation and prevents similar mismatches in future scenarios.
