/**
 * Plugins Manager E2E Tests
 *
 * Tests the plugins manager admin page at /plugins-manager.
 * Verifies that the page renders, displays plugin info, and
 * supports enable/disable toggling.
 *
 * This test exists because the plugins page previously crashed due to
 * incorrect API response envelope unwrapping (fetchPlugins returned
 * { items: [...] } instead of [...]) -- a bug that component tests
 * never caught because they mock fetchPlugins at the module level.
 *
 * The e2e fixture configures a color plugin (id: "color", version: "0.0.1").
