Greptile Summary

This PR migrates the GroupCreateUpdateModal from v2 component primitives (Modal, ModalContent, FormControl) to their v3 equivalents (Dialog, DialogContent, Field, FieldLabel, FieldError), and adds RoleOption as a custom renderer for the role FilterableSelect.

• The dialog's onOpenChange handler now conditionally calls reset() only on close (if (!isOpen) reset()), fixing a pre-existing issue where resetting on open would briefly wipe pre-populated form values before the useEffect could repopulate them.
• The isCreateMode flag is extracted as a named variable for cleaner conditional text rendering, and button order follows the standard v3 dialog pattern (Cancel first, Submit second).

Confidence Score: 5/5

Straightforward UI component migration with no logic changes to the underlying create/update API calls; safe to merge.

The change is a targeted swap of v2 dialog and form-control primitives for their v3 counterparts. The API mutation logic, form schema, and popup state management are all unchanged. The conditional reset() fix is a clear improvement. No new external inputs, network calls, or data-handling paths are introduced.

No files require special attention.
