Disks: eMMC is one device, not three, and reports wear from its own registers
mmcblkNboot0/boot1/rpmb are hardware areas of the chip; hide them on Disks and Dashboard. Badge eMMC/SD instead of SSD. smartctl cannot talk to MMC, so read life_time and pre_eol_info from /sys instead of showing its error. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
