fix(desktop): add GTK portal so file dialogs work

Home-manager's Hyprland module enables `xdg.portal` and pins the portal
search dir to the user profile with only the Hyprland backend, which has
no FileChooser implementation. File dialogs in Chromium/Electron apps
(signal, brave) fail with a DBus "No such interface
org.freedesktop.portal.FileChooser" error. Add `xdg-desktop-portal-gtk`
at the home-manager layer (system-level extraPortals aren't in the pinned
dir) and route FileChooser to it.
