Slideshow: a site whose path is a local folder (/home/kiosk/photos/, or
any existing directory) plays its images full-screen instead of showing
Chromium's directory listing. kiosk-app/slideshow.js maps the folder URL
to slideshow.html (resolveSiteUrl - used where main.js loads a view and
where attachView re-checks the configured URL) and pushes the image list
into the page from the main process (the page has no fs access), re-read
every minute so added/removed images show up without a restart. Natural
file-name order, crossfade, letterboxed by default; optional
slideshow.json in the folder: interval, shuffle, fit, transition,
recursive. provision_install_app already copies kiosk-app/*.js/*.html,
so new installs and Advanced -> Upgrade pick it up.
Electron: ^42.0.0 -> ^44.0.0. Electron supports the latest three majors
(44/43/42), so 42 drops out when 45 ships. Checked the 43/44 breaking
changes against kiosk-app: nothing it uses changed (no clipboard,
safeStorage, net.request, utilityProcess; BrowserView is deprecated but
still present through 46). The offline bundle builder now retries
Electron's install.js download, which crashes outright if a large
download is cut off mid-stream.
Tested with the real main.js on Electron 44.5.1 under Xvfb + Openbox:
slideshow fills the screen, cycles in order (01, 02, 10) skipping a .txt
file, honours slideshow.json, and an image added mid-run joined the
rotation after the refresh. Offline bundle rebuilt with Electron 44.5.1.

The keyboard-type IPC handler set input.value directly and dispatched a
plain "input" event. React (and similar frameworks) patch the value
setter on input/textarea instances to track the last value they set;
setting el.value directly updates that tracker too, so React never
detects a real change and its controlled state stays empty. The next
re-render (moving focus to another field, toggling a checkbox, etc.)
then redraws the input from that stale empty state, wiping out
whatever was typed. Route the writes through the native value setter
instead so the tracker stays out of sync and the dispatched event
actually reaches the framework's handler.
Also give the "Tab" key its own handler that moves focus to the next
focusable element, instead of falling through to the generic branch
that typed the literal word "Tab" into the field.

Until now ./install.sh only managed an already-installed kiosk;
ubuntu-based-kiosk.sh was still the only path from a bare Ubuntu Server
box to a running one. install.sh now provisions from scratch too:
packages, kiosk user, Node.js/Electron, LightDM+Openbox autologin,
audio/video/HDMI/power-button hardware setup, and the firewall, then
hands off to the already-migrated Core Settings/Advanced menus for
initial configuration instead of reimplementing that logic again.
- lib/provision.sh: the new provisioning flow, built mostly by calling
existing menus (core_settings_menu, emergency hotspot, virtual
consoles) - cuts it to ~300 lines against the legacy script's
~4,000-line first_time_install().
- lib/electron.sh: electron_install_binary() extracted out of
menus/advanced_electron.sh so provisioning and the existing "Fix
blank screen" action share one implementation.
- kiosk-app/ and provision/files/: the Electron app source and every
system template file, extracted byte-for-byte out of
ubuntu-based-kiosk.sh's heredocs into real files.
- Found and fixed a bash set -e gotcha along the way: testing a
multi-statement function as an if-condition (`if ! some_func; then`)
silently exempts everything inside that function from set -e for the
duration of the call. Fixed in the new provisioning code and in
menus/advanced_electron.sh's pre-existing repair action, which had
the same shape.
