test: await completed ChatGPT sign-in and consent saves

Replace arbitrary event-loop budgets in two release-gate tests with fresh per-attempt sign-in notifications and the actual consent control reply, bounded by a clear watchdog. Retain all final-state assertions and explicitly verify successful connected/error-free completion.

Controlled token/save gates demonstrate both old 100-turn waits return before completion; the corrected waits remain pending and retain the final persistence/UI assertions after release. Add small watchdog result/error/timeout tests. No production, workflow or dependency changes.

Isolated checks: focused 87/87, full suite once 2517/2517, full ESLint and typecheck. The full run preceded three runtime-erased non-null array-index annotations; focused tests/typecheck/full ESLint passed again on final source.
