//  1. Weather, Music, Stocks and Leaderboard are registry entries (`weather`)
//     whose manifests declare another id (`ledmatrix-weather`). The plugin
//     list, its config section and /plugins/toggle know them by that id, but
//     the button enabled the registry id: /plugins/toggle answered 404
//     "Plugin not found" and the plugin stayed disabled behind "installed,
//     but enabling it failed". It now enables the id the install answer
//     names (`plugin_id`), or, from an answer without one, the installed
//     entry the store entry matches (its id, plugin_path name or aliases).
//
//  2. Reinstall (the same button on an installed plugin) enabled it too, so
//     reinstalling a plugin the user had switched off switched it back on.
//     Only a fresh install enables.
//
// Runs the whole of plugins_manager.js in the sandbox against a fake API.
