Fix installed plugins view to show plugins installed from store

- Add logic to check installed plugins that don't have source directories
- Fixes issue where PM2 Manager (installed from store) wasn't showing in installed list
- Now shows all installed plugins regardless of whether they have source in /home/cyberpanel/plugins/
- Prevents duplicate plugin entries by tracking processed plugins
