Add a "Bulk Add" flow for the grok-cli provider, mirroring the existing
codex one: paste a JSON array/object or drag-drop multiple .json files,
then create all OAuth connections in a single call.
- BulkImportGrokCliModal: flexible JSON parsing (array, single object,
{accounts:[...]}, concatenated objects) + multi-file upload
- POST /api/oauth/grok-cli/bulk-import: serial createProviderConnection,
snake_case/camelCase token fields, email backfilled from id_token or
access_token, authMethod "device_code" to match the login flow
