feat: Add table listing and DSL retrieval processes

- Implement processList to return all loaded tables and processDSL to retrieve the DSL of a specified table.
- Add unit tests for the new processes to ensure correct functionality and data integrity.
- Update process registration in exportProcess to include the new operations.
