Import a public Google Form as a Clipform
Fetches a public Google Form, parses its question structure, and creates an equivalent Clipform in draft mode. Best-effort: unsupported question types (grid, date, time, linear scale, file upload) are skipped and reported in `import_summary.skipped_details`. Supported mappings: short answer/paragraph → open, multiple choice/dropdown → choice (single), checkboxes → choice (multiple), title/description → button. No auth required. Requires `workspace_id`.
No importable questions found (form_id is null)
