debug(05-jamtrack): add package structure logging for debugging

Added console.log statements to inspect the actual package data structure
returned from the REST API. This will help identify:
- Correct field names (snake_case vs camelCase)
- Actual values for file_type, encrypt_type, sample_rate
- Available packages for debugging "No compatible package" errors

Also updated the compatiblePackage search to check both naming conventions:
- pkg.file_type or pkg.fileType
- pkg.encrypt_type or pkg.encryptType
- pkg.sample_rate or pkg.sampleRate

This is a temporary debugging commit to diagnose the package matching issue.
