test(central-ui): Playwright Flow Debugger live run + localStorage restore against the rig

An ephemeral inbound method (created and deleted through the CLI, with a never-taken
Route.To branch so prediction resolves a route target) is run live in a real browser through
the fixture's /auth/login; the reload test drives the OnAfterRenderAsync localStorage restore
and then proves the page is still interactive. Both fail on the pre-fix image at the
'Predicted' wait (the circuit deadlock) and pass on the fixed one.
