fix(flatpak): bundle libayatana-appindicator for tray icon support (#556)

The Flatpak was failing to load because libayatana-appindicator3 is not
included in org.gnome.Platform runtime. This adds the required modules:
- libayatana-ido
- libdbusmenu-gtk3
- libayatana-indicator
- libayatana-appindicator

Fixes panic: 'Failed to load ayatana-appindicator3 or appindicator3 dynamic library'
