A plugin can no longer replace the site palette. "Designpaket übernehmen"
wrote the plugin's colours, fonts and buttons into the website for good:
no confirmation, no way back, right next to a switch that is safe to flip.
Colours belong to the design screen, where they have a preview and one-step
undo, so the feature is gone rather than guarded (ADR 105).
Removed: PluginRegistry::themePackage() and applyTheme(), "theme" in the
manifest and in the plugin structure, the admin_plugin_theme route and the
Theme dependency of PluginAdminController, the button and the design-package
line on the "Plugins" screen, and plugins/nachtblau. A manifest now needs at
least one block, one route or one preset.
The test says the opposite of what it used to: switching a plugin on and off
leaves both the design and the content alone.
