The installer failed with:
deploy-disk.sh /dev/vda ... workstation --boot
error: --boot must be bios|efi (got --boot)
Two bugs:
1. deploy-disk.sh treated $4 as the bare boot value, but every caller
(installer, build-image.sh, install.sh) passes "--boot <val>", so $4
was the literal "--boot". It now parses "--boot <bios|efi>", accepts a
bare positional too, and falls back to the BOOT build variable. This
also fixes build-image.sh / install.sh, which had the same mismatch.
2. installer/arcline-installer built the boot ComboBox with append(id,text)
arguments swapped, so get_active_id() returned "UEFI (grub-efi-amd64)"
instead of "efi". Fixed the id/text order.
