Blake Ridgway 1618897bc2 fix: deploy-disk.sh --boot argument parsing + installer combo ids

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.

Arcline graphical installer

installer/arcline-installer is the GTK3 frontend that the live ISO boots into. It is a thin wrapper around scripts/deploy-disk.sh — the same, auditable deploy core the scripted installer and disk-image builder use.

How it works

 boot ISO → live session (Xorg on vt1) → installer window
   pick target disk → confirm device path → deploy-disk.sh → reboot

The installer extracts install/arcline-<edition>.tar.xz (the clean rootfs archive staged on the ISO by build-iso.sh) to a temp dir and runs:

/usr/lib/arcline/scripts/deploy-disk.sh <device> <rootfs> <edition> --boot <bios|efi>

streaming the deploy log into the window. Everything destructive lives in deploy-disk.sh, which the live image ships (with its dependencies) at /usr/lib/arcline:

/usr/lib/arcline/scripts/{common,deploy-disk,apply-fstab}.sh
/usr/lib/arcline/btrfs/init.sh
/usr/lib/arcline/editions/{server,workstation,cloud}/fstab

The layout mirrors the repo so the scripts' own path resolution works unchanged.

Building the ISO

make iso-server            # or iso-workstation / iso-cloud

build-iso.sh builds the clean rootfs, then build-live.sh clones it into build/rootfs/<edition>-live and layers on live-boot, a minimal X session (openbox), the installer, and the deploy tooling. The live session rootfs is never what gets installed — the installer always deploys the clean archive, so what you end up with on disk is exactly the hardened system, not the live session with the installer in it.

Autostart

overlays/live/etc/systemd/system/arcline-installer.service starts arcline-installer-session on boot. Modern Xorg (trixie 21.1.x) refuses to run as root, so the session script:

hands the dedicated console VT to liveuser (chown, since udev leaves VTs 620 root:tty which isn't readable by the tty group),
starts Xorg as the unprivileged liveuser on vt1,
grants root display access (xhost +SI:localuser:root),
runs the installer as root (it needs root for deploy-disk.sh).

When the installer exits, X and the session end.

Manual run (for development / on a box without the ISO)

# on any Arcline system with the deploy tooling:
sudo /usr/local/bin/arcline-installer

The app refuses to run as a non-root user and errors if the deploy tooling is missing.

Notes

Disk discovery uses lsblk (util-linux); read-only devices are hidden.
Confirmation mirrors scripts/install.sh: you must type the exact device path before the install button will proceed.
Root is hidden by design; the installer runs before any user session.
For UEFI machines, pick "UEFI" boot mode (or use BOOT=efi when building); see docs/secureboot.md for signing the boot chain for Secure Boot.
