fix: add e2fsprogs and cryptsetup-initramfs to rootfs

ISO boot failed in emergency mode because:
- fsck.ext4 binary missing (no e2fsprogs in rootfs)
- LUKS data volume never opened (no cryptsetup-initramfs in initramfs)

Both packages were in the installer debootstrap but not the target rootfs
Dockerfile. The initramfs regeneration at install time now includes LUKS
support since cryptsetup-initramfs is present.
