feat(installer): richer disk picker (vendor, model, serial, type)

Replaces the bare `NAME SIZE` lsblk listing in select_disk with a
six-column table — NAME, SIZE, TYPE, VENDOR, MODEL, SERIAL — aligned
via column -t. TYPE is derived from ROTA + TRAN (NVMe / USB / SSD /
HDD). Empty vendor/model/serial fields render as `--` instead of
collapsing the alignment. Filters loop, ram, zram, sr devices.

Roadmap row moves to Shipped.
