Claude 0e42de1cda Add vpn-data-mount: SMB mount from a NetBird-connected home box
Offered right after NetBird setup during required/base setup, matching
the requested flow (base packages -> NetBird -> data mount). Repeatable
by design rather than a one-shot step, since different services can have
data on different home boxes — asks for a home box IP every time and can
be run again for additional boxes/shares.

Flow: test for existing passwordless SSH first (covers "both boxes already
share a key via GitHub import, or any other means" for free — if it
already works, nothing else runs). If not, generate an SSH keypair and
offer ssh-copy-id or a manual/GitHub-import fallback (ssh-import-id, the
same mechanism base.sh's own SSH setup already uses) — needed because a
home box that took base.sh's "disable password login" option won't accept
ssh-copy-id at all. Once passwordless SSH works, use it to remotely
install and configure Samba on the home box for a chosen path, then mount
it locally over CIFS with a tagged /etc/fstab entry.

SMB over NFS/SSHFS per this session's direction: not a "huge" speed gap
for normal use, and SSHFS's own encryption is redundant overhead once the
VPN tunnel already encrypts everything. Guest-accessible (no separate
Samba credentials) since the VPN is the real access control — only
NetBird-connected peers can reach the home box's NetBird IP at all.

Also:
- cifs-utils added to base.sh's always-installed packages, same reasoning
  as Docker/Compose being unconditional there instead of installed lazily
  on first mount.
- is_installed()/install_count() in setup.sh gained a vpn-data-mount case
  (state lives in tagged /etc/fstab entries, not $DOCKER_DIR, since this
  isn't a Docker service) — mirrors wordpress's "count real instances"
  handling rather than a flat 0/1.
- Every SSH call in the new service explicitly runs as $ACTUAL_USER
  (sudo -u), not root — the script itself runs as root throughout, but the
  SSH key lives in $ACTUAL_HOME/.ssh, so a bare `ssh` call would silently
  use root's own ~/.ssh instead and never find it. Caught by review before
  this shipped, not after.
- UNATTENDED mode skips outright with a message instead of spinning
  forever on prompt_text's always-blank default under --unattended, since
  none of this flow's prompts (home box IP, remote path, ...) have a
  sane non-interactive default.
