…sponse types

The Export method now properly handles all possible response types from AuthExportLoginToken:
- AuthLoginToken: normal case, returns new token
- AuthLoginTokenSuccess: token already accepted, returns error
- AuthLoginTokenMigrateTo: migration needed, returns MigrationNeededError

Previously only AuthLoginToken was handled, which could cause unexpected type errors.

AuthLoginTokenSuccess indicates successful authentication, not an error.
Return empty token instead of error when login token was already accepted.

…enSuccess case

…d for AuthLoginTokenSuccess case

- Add tests for MigrationNeededError.Error method (0% -> 100%)
- Add tests for OnLoginToken function (0% -> 100%)
- Add tests for Token.Image method (0% -> 75%)
- Add tests for Import method with migration scenarios (43.5% -> 82.6%)
- Overall coverage improved from 67.0% to 84.6%

…eived

When Export returns empty token (AuthLoginTokenSuccess case), Auth method
should wait for the loggedIn signal before calling Import, ensuring proper
synchronization with the login flow and fixing test failures on macOS Go 1.23.
