test(showcase/langgraph-python): rewrite open-gen-ui and open-gen-ui-advanced to iframe-presence assertions

Drop the 5 cross-origin contentFrame() / page.on('console', ...) skipped
assertions across the two specs — sandbox=allow-scripts only blocks host
introspection of the iframe DOM, and console-spying on the host page
catches no inner-iframe logs. Replace with iframe-presence assertions:
each pill click must produce iframe[sandbox*='allow-scripts'] with a
non-empty srcdoc (or src) attribute. That is the load-bearing signal
that the open-generative-ui pipeline mounted SOMETHING.

Rewrite each suggestion message string as a short verbatim label that
doubles as a deterministic aimock fixture key (paired with the new
fixtures in showcase/aimock/d5-all.json). Drop pill-title parentheticals
per the cosmetic note in lgp-test-genuine-pass.md so titles read as
natural human prompts; keep the message field aligned with the fixture
key.

Final test counts: 5 minimal (page-load + 4 pill-iframe), 4 advanced
(page-load + 3 pill-iframe). All .skip() removed. The sandbox-function
round-trip (evaluateExpression / notifyHost) is intentionally not
asserted here — that requires a same-origin sandbox option or a
host-side spy on the runtime's sandbox-function-call event, both
deferred to a follow-up.
