Siavash Sameni 5cd7a20152 fix(ui): disable WebView pinch-zoom and desktop right-click menu ...

Two small WebView hardening tweaks that apply to both Android (Tauri
mobile) and desktop (Tauri) since the frontend is shared:

- index.html viewport meta now sets maximum-scale=1.0, minimum-scale=1.0,
  and user-scalable=no. This stops users on Android from pinch-zooming
  out of the fixed-layout UI. Desktop is unaffected because the Tauri
  WebView ignores pinch gestures anyway.
- main.ts installs global listeners that preventDefault on contextmenu
  (kills the browser-style right-click menu that exposed Inspect /
  Reload / Back / Forward entries on desktop), keydown Ctrl+-/+/0
  (stops keyboard zoom of the fixed layout), and gesture* + ctrl-wheel
  events (trackpad pinch on WebKit + Chromium respectively).

Dev tools remain accessible via F12 / Cmd-Opt-I keyboard shortcuts —
only the right-click entry point is suppressed. Android has no
right-click so that part is a no-op there.
