feat(cli): add enablePlugins to setup wizard and ENABLE_PLUGINS mapping

Mirrors the host project's new `features.plugins` flag: env-config now
reports plugins in FEATURE_ENV, and setup.ts exposes enablePlugins in
ProjectConfig, DEFAULT_CONFIG, FEATURE_ENV_VARS and MODULE_REMOVALS
(removes marketing/dashboard plugin pages, /api/plugins, lib/plugins and
the plugin components when the flag is false). The marketing preset
leaves plugins on by default.
