Update the configuration of an existing column. Only the fields you include in the request body will be changed. Use this after creating a column from a template to fill in required fields like dependencies, AI prompts, or task input mappings. Column structure is automatically validated and fixed after each update. Any applied fixes are returned in the appliedFixes field so you know what was corrected. Requires a Bearer token.
