fix(gtk): let the appearance drawer own the icon and cursor themes

templates/gtk/index.theme.in named IconTheme and CursorTheme, and it is
installed whole-file into ~/.themes/udt/index.theme, which the drawer's Icons
tab never rewrites. Every switch there left this file naming the old theme.
Both keys are dropped: gsettings wins over a metatheme hint on Wayland, so the
drawer's value stands on its own.

templates/qt-gtk/{gtk3-settings.ini,qt5ct.conf,qt6ct.conf} were checked and
are not a conflict: nothing installs them, and install.sh only seds
gtk-theme-name into the live gtk-3.0/settings.ini. Each now says so at the
top, so the next reader does not have to establish it again.

TODO-icons.md records the audit, including the three consumers outside this
repo that resolved icons against a hardcoded theme name.
