- Change RequestAuthenticatorError enum to public in RequestAuthenticator.swift

- Import `RequestAuthenticatorError` in `ApplicationPasswordAuthorizationWebViewController.swift`
- Update error navigation method name to `navigateToApplicationPasswordDisabledUI` in `ApplicationPasswordAuthorizationWebViewController.swift`
- Modify error handling logic to differentiate between `applicationPasswordNotAvailable` and other errors in `ApplicationPasswordAuthorizationWebViewController.swift`
