[sc-323687] Feat: Add Cobuild support metadata

+- API Connect performs one API call per input row and writes the extracted rows from each response, including paginated responses, to the output dataset.
+- Always set `endpoint_url` and select at least one `parameter_columns` column. Selected columns become `{{column_name}}` template variables across request fields; `parameter_renamings` changes their template names.
+- `auth_type=null` supports either no authentication (`credential` unset) or a generic credential preset. A secure authentication type requires its corresponding visible preset.
+- API Connect automatically injects an API-key preset into the header or query parameter configured by the user in that preset. Do not add the API key again to request fields.
+- Use the dot-separated `extraction_key` when response rows are nested under a JSON path.
+- Keep `raw_output=true` when each response item should be preserved as raw JSON instead of flattened into columns.
+- Select the pagination mechanism from the target API's documentation; do not infer one from the endpoint shape. Relative next-page URLs require `next_page_url_base`, page pagination requires `extraction_key`, and offset or page pagination requires `skip_key`.
