    fix: deploy new factory with old sso beacon

    The problem was in the upgrade process a new SSO beacon proxy was
    deployed for the new implemention instead of re-using the existing one.
    This was because it used the era-sepolia.json which only contains the
    contracts necessary for the auth-server and didn't have the SSO Beacon
    address.
    The SSO beacon address needs to stay the same because its address is
    specifically allowed by the sequencer.

    Might also need to update + fund the paymaster, will test in PR.

* fix: undo localhost change

This was helpful for debugging locally to avoid CORS, but not really
long-term necessary!
