feat: match any touch screen for libinput, not just Wacom "Finger" devices

Drop the MatchProduct "Finger" restriction from the xorg libinput rule,
leaving only MatchIsTouchscreen "on". MatchIsTouchscreen is set by udev
from hardware capabilities, so it matches finger touch screens of any
brand (ELAN, Goodix, eGalax, Wacom, etc.) while never matching keyboards,
mice, or pen/stylus digitizers (which are tagged as tablets, not
touchscreens). This makes the script work on any touch hardware without
hardcoding device names. Behavior on existing Wacom machines is unchanged
since their finger device matched either way.

 **Recent Updates (v1.0.3):**
 - **Touch input fix (keyring):** added `--password-store=basic` to the Electron launch. Under LightDM autologin the GNOME keyring stays locked; when Chromium accessed it, the keyring unlock dialog grabbed all keyboard/touch input — the kiosk rendered fine but ignored every tap and keypress. This flag stops Electron from using the keyring, so the dialog never appears.
-- **Touch gesture fix (libinput):** finger touch screens are now forced to the `libinput` driver via `/etc/X11/xorg.conf.d/99-finger-libinput.conf`. The `wacom` driver only does single-touch pointer emulation and never passes real multitouch to Chromium, so 1-finger and 2-finger swipe gestures could not fire. libinput delivers proper multitouch; the pen/stylus stays on the wacom driver.
+- **Touch gesture fix (libinput):** any touch screen is now forced to the `libinput` driver via `/etc/X11/xorg.conf.d/99-finger-libinput.conf` (matched by hardware capability, so it works on any brand and never affects keyboards, mice, or the pen/stylus). Some drivers — notably `wacom` — only do single-touch pointer emulation and never pass real multitouch to Chromium, so 1-finger and 2-finger swipe gestures could not fire. libinput delivers proper multitouch.
 - **Upgrade reliability:** `start.sh` is now refreshed on every upgrade alongside `main.js` and `preload.js`
 - **Upgrade fix:** node_modules no longer wiped during upgrade — preserves the ~120MB Electron binary so upgrades don't fail on slow/unreliable connections
 - **Authelia fix:** 10-second timeout on Authelia login fetch prevents white screen when Authelia is slow to respond
