Plugins: fix 404 - add plugin roots to sys.path before loading URLs

- pluginHolder/urls: insert /usr/local/CyberCP and source paths at top of module
  so __import__(plugin_name + '.urls') finds plugin packages (fixes No module
  named 'X.urls'). Register plugin routes before catch-all help route.
- pluginHolder/views: add debug_loaded_plugins API and log full traceback on
  plugin import failure. panelAccess/emailMarketing settings/ routes added
  earlier; cspManager resilient to missing DB table.
