Fix auto mode to handle Dict-based problem lists with metadata

In auto mode, the server now properly handles problem lists that
contain Dicts with metadata (new format) instead of just strings.

Changes:
- Extract "id" field from Dict when adding module prefix
- Preserve all metadata when creating prefixed problems
- Maintain backward compatibility with string-based problem lists

This fixes the issue where auto mode would stringify the entire Dict
instead of just the ID when prepending module prefixes.
