fix(console): DeviceAuthPage keeps device context through the login redirect (#1674)

The signed-out branch rebuilt the redirect from user_code alone, dropping
runtime_name/runtime_version — a signed-out approver never saw what
device they were authorizing (found in the bind-v2 E2E).

+DeviceAuthPage preserves the full query string (runtime_name / runtime_version device context) through the login redirect — previously only user_code survived, so a signed-out approver never saw what device they were authorizing.
