Pull Request Overview

Adds an option for users to retrieve only the database export commands instead of running the full migration, with support in both UI and API, and fixes a malformed events_data query.

• Exposes a new “Get only database export commands” radio button in the export drawer
• Implements create_export_commands in the backend and wires up only_commands in the API
• Updates frontend to download a .sh script when the “only export” option is selected

• [nitpick] Using a raw number (2) for the export mode is a magic value. Consider defining a constant or enum for export types to improve readability.
