samples: net: azure_iot_hub: disable Partition Manager; NS and MCUboot layouts
Kconfig.sysbuild PM default n. nrf7002dk NS overlay and .conf for static partitions and SRAM; nrf54lm20dk A/B NS overlays (image-1 on external flash, image-0 on RRAM) and drop redundant NS .conf lines; nrf7002dk and nrf54lm20dk MCUboot board snippets for external flash / partition alignment. Changelog entry. Co-authored-by: Cursor <cursoragent@cursor.com> Signed-off-by: Pavel Vasilyev <pavel.vasilyev@nordicsemi.no>
