fix: remove beta labeling from comfy cloud badges (#9184)

Remove the BETA label from Comfy Cloud badges while keeping the `Comfy
Cloud` text.

This updates both paths that render Comfy Cloud badge content:
- `src/extensions/core/cloudBadges.ts` (topbar extension badge path)
- `src/components/topbar/CloudBadge.vue` (reusable cloud badge used in
subscription UI)
