:recycle!: Normalize UDN comparison and improve WebRenderer detection

- Fix renderer filtering logic to normalize `udn` and id by stripping 'uuid:' prefix
- Replace fragile model_name-based detection with reliable friendly-name check for WebRenderers ('Web Audio – ' prefix)
- Add `manufacturer` field to renderer types and registry
- Update badge count in UnifiedControlView.vue to use filtered renderers
