Badge for cloud environment (#6048)

This pull request introduces a new system for displaying
environment-specific badges in the application's top bar, with a focus
on supporting a "Comfy Cloud" badge in production environments. The
changes include new badge types, extension support, UI components, and
environment detection logic to ensure badges are only shown in
appropriate contexts.

**Topbar Badge System**

* Added a new `TopbarBadge` type and support for topbar badges in the
`ComfyExtension` interface to allow extensions to specify badges for the
top bar.

* Created a Pinia store `topbarBadgeStore` to aggregate topbar badges
from all registered extensions for display.

**UI Integration**

* Added a new `TopbarBadges.vue` component to render topbar badges and
integrated it into the top menu bar UI.

* Updated CSS variables and menu styling to support the new badge
visuals.

**Environment Detection and Extension Registration**

* Added a runtime environment detection utility to determine if the app
is running in production or staging, replacing the previous build-time
constant approach.
* Registered a new `cloudBadge` extension that conditionally adds a
"Comfy Cloud" badge with a "BETA" label when running in production.
