fix(hooks): always persist plugin hook config state, even when empty

When all plugin hooks are removed (user disables/uninstalls plugins),
hooksConfigs becomes an empty array. The previous guard
(hooksConfigs.length > 0) skipped setPluginHooksConfigs(), leaving
stale plugin hooks active in pendingPluginHooksConfigs. Now we always
call setPluginHooksConfigs() so empty configs properly clear the
pending state and invalidate the cache.
