fix(desktop): prevent Cmd+R / Ctrl+R / F5 from reloading the page

In a desktop app an accidental page reload destroys in-memory state
(tabs, drafts, WS connections) with no URL bar to navigate back.

Add a before-input-event listener on the main BrowserWindow that
intercepts Cmd+R / Ctrl+R (with or without Shift) and F5, calling
preventDefault() to block the reload. DevTools refresh still works.
