fix: use absolute icon path and place icon outside asar on Linux

The hicolor icon theme index only lists sizes up to 512x512, so an icon
installed only at 1024x1024 is invisible to GNOME/KDE's theme resolver,
causing both the app launcher and taskbar to show a generic icon.
Additionally, BrowserWindow.icon cannot be read by the window manager
when the file is inside app.asar.

- extraResources: copy logo_larger.png to resources/ (outside asar) so
  it lands at /opt/Automaker/resources/logo_larger.png on install
- linux.desktop.Icon: set to the absolute resources path, bypassing the
  hicolor theme lookup and its size constraints entirely
- icon-manager.ts: on Linux production use process.resourcesPath so
  BrowserWindow receives a real filesystem path the WM can read directly
