refactor(auth,etcd): reduce nesting depth to comply with 3-level max

Browse Source 
- service/auth/login.rs: extract auth_find_user() helper combining
  username + email lookup, reducing login flow from 5 levels to 3
- etcd/register.rs: extract run_keep_alive_stream() and
  renew_lease_and_reregister() from spawn_keep_alive(), reducing
  max nesting from 7 levels to 3
