feat(_update): replace watchtower with custom nightly update script

Removes the watchtower container in favour of a host-side script that
runs daily at 2:00 AM via systemd timer.  Mirrors the _backup pattern:
auto-discovers stacks, pulls images, recreates changed containers,
prunes dangling images, and notifies via n8n → Telegram.
