live: override tuna-installer flatpak desktop entry for Dakota branding

Place /usr/local/share/applications/org.bootcinstaller.Installer.Devel.desktop
which is earlier in XDG_DATA_DIRS than the flatpak export path. This renames
the app to 'Dakota Installer' and swaps the icon to the dakota hicolor theme
icon, so only one consistently-branded entry appears in the GNOME dock.
