_GeneralTab and _PluginConfigTab inherited from Widget (height: auto), causing the inner VerticalScroll to get height: 1fr of an auto-height parent, which collapsed to 0. Fix: inherit from VerticalScroll directly and remove the inner wrapper. _PluginsTab gets DEFAULT_CSS to fill its TabPane. Also replace $text-muted (invalid in Textual 8.x) with $foreground 50%.
