refactor(api): align generic data item route with new models

Replaces all references to 'category' with 'topic' and 'app_config' with 'remote_config' in the item-specific data handler at `/api/v1/data/[id].dart`.

This change ensures the GET, PUT, and DELETE operations for individual items correctly use the updated `Topic` and `RemoteConfig` models and their corresponding repositories.
