[native][web] Handle use_new_flow for Identity V1 login calls

Summary:
Address [[ https://linear.app/comm/issue/ENG-9717/support-use-new-flow-for-v1-login | ENG-9717 ]]

For V1 login we can reuse existing logic for `unsupported_version` to also work for `use_new_flow`. Desired behavior is the same.
Updated all Identity callsites.

Depends on D13954

Test Plan: Mocked local Identity to return `use_new_flow` for all login RPCs. Confirmed that login attempt on device fails and a message is displayed
