Add zfssnapshot and zfsrollback scripts to ISO

Copied from archsetup to make these tools available on the live ISO
for rescue scenarios and post-install management.

zfssnapshot:
- Creates recursive snapshots across all pools
- Timestamps with descriptive labels (YYYY-MM-DD_HH-MM-SS_description)
- Integrates with grub-zfs-snap for boot menu updates

zfsrollback:
- Interactive fzf-based snapshot selection
- Two modes: single dataset or all matching datasets
- Safety warnings showing what will be destroyed
- Special genesis rollback warning
