test: approve a patch in the live app test

[guillaumegay13]

✨ What changed

• The live test opens the issue, then approves a clamp patch as an operator.
• Operator credentials come from MNFST_TEST_OPERATOR_EMAIL / _PASSWORD, defaulting to the dev seed.
• It now covers aiohttp and urllib too: 5 clients succeed, plus the failed and inconclusive cases.
• Each run uses a letters-only path segment, so it gets its own issue.

💭 Why

The app returns no_patch until an operator approves a patch, so test_live_app.py failed at its first call against any current app, whatever the SDK did.

📝 Notes

• Stacked on feat: heal and track urllib.request calls #46. Merge feat: heal and track urllib.request calls #46 first, then retarget this one to main before merging.
• Passed 4 runs against a local app from mnfst/app main. Still skipped in CI without MNFST_TEST_APP_URL.
• The app keys issues by path, templates hex or digit segments and ignores the port. An approved patch serves every project, hence the fresh segment per run.
