feat(gooddata-sdk): [AUTO] add grand_totals_position to ExportSettings

[yenkins-admin]

Adds optional grand_totals_position field to ExportSettings in the gooddata-sdk, exposing the new grandTotalsPosition enum from the upstream OpenAPI specs.

Problem ID: P011 | Workflow: https://github.com/gooddata/gdc-nas/actions/runs/22995241596

What changed in gdc-nas

Commit 36a823e added a new grandTotalsPosition enum field (values: pinnedBottom, pinnedTop, bottom, top) to the Settings sub-object of TabularExportRequest across three OpenAPI specs (automation, export-controller, metadata-api). The field is optional and takes precedence over a position embedded in the visualization definition; the export-controller falls back to the visualization's value when the field is null or UNSPECIFIED. The change is also propagated through the gRPC export.proto, the Kotlin gRPC client extension, and the Python tabular-exporter microservice.

What was implemented in SDK

• Defined GrandTotalsPosition TypeAlias (Literal['pinnedBottom', 'pinnedTop', 'bottom', 'top']) for type safety.
• Added optional grand_totals_position: Optional[GrandTotalsPosition] = None field to ExportSettings, wired through as_api_model() to ApiSettings.
• Exported GrandTotalsPosition from the public gooddata_sdk.__init__.
• Added a parametrized unit test test_export_settings_grand_totals_position verifying the field round-trips correctly through the SDK model layer.
