refactor(routes): replace route retrieval with GetIncludeExcluded

- Updated route retrieval in the API and idle watcher to use GetIncludeExcluded, allowing for the inclusion of excluded routes.
- Simplified the route status aggregation logic by directly using GetIncludeExcluded for display name resolution.
- Removed redundant code that separately handled excluded routes, streamlining the route management process.
