fix(test): retry consent handling in login_flow_static_client_token

The oidc app does a JS-driven re-authorize chain after login
(/apps/oidc/redirect → /apps/oidc/authorize → /apps/oidc/consent).
wait_for_load_state("networkidle") can fire during the brief gap before
the consent page renders, so a single _handle_oauth_consent_screen call
right after login often misses the consent div and the OAuth flow
deadlocks waiting for a callback that never arrives.

Move consent handling inside the callback-wait loop and poll for either
the consent page or the callback hit. Loop bound bumped to 60s to give
the JS-driven re-auth headroom.

Confirmed locally: integration test now passes against docker compose
--profile login-flow with the static OIDC client.
