Pull request overview

Adds nRF54LS05A (nrf54ls05dk/nrf54ls05a/cpuapp) MCUboot/DFU enablement by extending existing nRF54L bootloader sample/test coverage and SoC-specific secure-boot defaults to include the LS05A variant.

Changes:

Switches the west manifest’s MCUboot revision to a PR ref for LS05A-related MCUboot work.
Extends multiple bootloader and DFU sample/test matrices to include nrf54ls05dk/nrf54ls05a/cpuapp.
Introduces LS05A-specific board overlays/Kconfig defaults/partition layouts used by sysbuild MCUboot and DFU samples.
