Community app dependency links use the official store route

[lucasilverentand]

Codex created this issue after verifying the behavior against the current UI source and a community app store.

Reproduction

1. Add a community app store containing app example-store-manager.
2. Give that app a manifest dependency on another app in the same store, such as example-store-service.
3. Open the manager app through /community-app-store/example-store/example-store-manager.
4. Select the dependency in the Requires section.

Current behavior

The dependency link navigates to /app-store/example-store-service, which fails because the app is not in the official store.

packages/ui/src/modules/app-store/app-page/dependencies.tsx hardcodes /app-store/${app.id}. select-dependencies-dialog.tsx contains the same route and a TODO noting that community apps need a different destination.

Expected behavior

When app.appStoreId is not umbrel-app-store, dependency links should navigate to:

/community-app-store/${app.appStoreId}/${app.id}

Official-store dependencies should continue using /app-store/${app.id}. The same route selection should be shared by the Requires section and dependency-selection dialog.
