refactor(router): consolidate entity details routes into a single route

- Replace separate routes for topic, source, and country details with a generic entity-details route
- Update route path to use parameters for entity type and ID
- Modify route builder to handle different entity types dynamically
- Update Routes class to reflect the new consolidated route
