feat(icons): read the icon theme from gsettings
The icon theme name was hardcoded in three places (bin/wb-icon,
modules/extras/taskbar.jsonc and install.sh), so switching themes in the
appearance drawer was silently reverted as far as this bar was concerned.
wb-icon now reads org.gnome.desktop.interface icon-theme and gains two modes
for install.sh: --path NAME prints one icon's absolute path, --theme prints
the resolved theme name.
Icons are resolved per name rather than by substituting a directory prefix,
because themes disagree about both subdirectory and file extension: the Suru
themes keep web-browser at categories/22/*.svg, elementary-xfce at
apps/22/*.png. Only a real GTK lookup knows the path.
styles/modules.css therefore carries @ICON:name@ placeholders and
modules/extras/taskbar.jsonc carries @ICON_THEME@, both filled at install
time. taskbar.jsonc is generated rather than symlinked for that reason, and
install.sh removes the old symlink first so the redirect cannot overwrite the
committed source.
A theme missing one of the twenty names fails the install at the --selftest
step rather than drawing empty pills.
