host: site themes are the host's (AppConfig::with_themes, commands::THEME)

Browse source 
theme_commands serves theme_get / theme_set / theme_preview / theme_scopes_get / theme_scopes_set
(shell-only, each checks its caller first; testkit::assert_theme_guards) over the theme state the
host now keeps: the owner's theme, account and pane themes, the Theme Builder preview. The app
only names its built-in themes and the two files (ThemeConfig). apply() themes every site tab
(script, cached Google font bytes, native background); page_scripts()/tab_background() serve a new
document; set_theme/set_scopes/set_preview are the app's own writers (backup import, dev mode).
A font install or removal re-themes the tabs in the host itself.
