feat(appearance): add the icon and cursor theme model

Lists themes from ~/.icons, ~/.local/share/icons and /usr/share/icons,
distinguishing cursor themes by cursors/ or manifest.hl. Icon previews
come from one GTK lookup process for every theme; cursor previews extract
left_ptr from a hyprcursor .hlc via unzip or from an Xcursor theme via
xcur2png. Application sets gsettings and the Qt configs, and rewrites the
cursor env in environment.lua.
