fix: add error code for app not found

Add utils::error::ErrorCode::AppNotFoundFromLocal error code to the
error message when Cli::info fails to find an application locally.
This change improves error traceability by providing a specific
error code instead of a generic message, enabling better error
handling and debugging capabilities.

Influence:
1. Test 'info' command with non-existent local applications
2. Verify error output includes the AppNotFoundFromLocal error code
3. Confirm error message text remains user-friendly
4. Test integration with error handling systems that rely on error codes
5. Verify no regression in existing info command functionality
