fixes intermittent test errors occrued due to lagcy token usage

[sandeepbarnwal]

Summary

Replace LAUNCHABLE_TOKEN with SMART_TESTS_TOKEN in test_codeceptjs.py to fix test failures in a scenario when SMART_TESTS_TOKEN is already set in the environment before executing uv run poe test-xml.

Problem

LAUNCHABLE_TOKEN is only a fallback in get_token(). If SMART_TESTS_TOKEN was already set in the developer's environment, it took precedence over the injected mock token, causing requests to hit unregistered mock URLs and producing empty output that failed json.loads().

Fix

Use SMART_TESTS_TOKEN (the primary token) so mock.patch.dict always overwrites any real environment value. It becomes consistent with every other test file in the repo.
