Install WiFi tools (wpasupplicant, iw) in the base kiosk install

Browse Source 
A default Ubuntu Server 26.04 install only gets wpasupplicant/iw when
WiFi is configured in the installer's network screen (they're not in the
server manifest otherwise). Without them netplan can't join a WiFi
network and Core Settings -> WiFi stops at "No WiFi tools found" - which
is exactly the offline-first case: install with no network, then use the
kiosk's WiFi menu to connect.

- Add wpasupplicant and iw to PROVISION_APT_PACKAGES, so first boot
  installs them in step 1 (from the offline bundle when there's no
  internet) - before Core Settings -> WiFi is offered. +1.6 MB in the
  bundle.
- wifi_menu installs them itself (via run_with_offline_fallback) if
  they're missing, instead of erroring with an apt command to run.

Bundle rebuilt: contains wpasupplicant and iw.

- **Offline installs** (`--offline`): the ISO carries every package (including CUPS printing and all printer drivers), Node.js 22, and prebuilt Electron/Web UI modules, so a kiosk installs with no internet. With internet it still installs current versions online. Addons → CUPS Printing (menu or Web UI) installs from the bundle by itself when offline.
- **Local files as sites:** an absolute path (`/home/kiosk/docs/menu.pdf`) shows a local page, PDF or image; a folder (`/home/kiosk/photos/`) plays as a full-screen **image slideshow** that picks up added/removed images within a minute. Works in both the Sites menu and the Web UI.
- **Fix: the first-boot kiosk setup never started on 26.04.** Its service was ordered after cloud-init's final stage, which itself runs after `multi-user.target` - an ordering cycle that systemd broke by dropping the kiosk setup. It also "conflicted" with the tty1 login prompt, which systemd can resolve the same way. Both removed; checked with `systemd-analyze verify` against 26.04's own units. Rebuild the ISO to pick this up.
- **WiFi tools in the base install:** `wpasupplicant` and `iw` are now installed (and bundled offline). A default Ubuntu Server install only has them if WiFi was set up in the installer; without them, Core Settings → WiFi couldn't connect an offline kiosk. The WiFi menu also installs them itself if missing.
- **Offline addons:** the `--offline` bundle now also carries LMS (Lyrion) + Squeezelite, Asterisk Intercom, VNC, WireGuard and the Emergency Hotspot; their normal installs use it automatically when there's no internet.
- **Emergency Hotspot fix:** by default it now starts only when the local network is unreachable (router *and* internet), not merely when there's no internet - on a LAN without internet it used to start on every boot. Existing setups keep the old check until Advanced → Emergency Hotspot → Reconfigure.
- **New: Core Settings → Time Server (NTP)** - use a time server on your network, go back to Ubuntu's, or set the clock by hand; for networks without internet.
