Add paired python_alloc scenarios asserting alloc-space and alloc-samples with thread-name labels, reusing the python_basic_memory workload. Gate grows from 12 to 14 scenarios.
Python 3.14 alloc profiles use Target.method stack frames and numeric thread IDs, so drop MainThread label assertions and update stack regexes.

Motivation
Allocation profiling (
alloc-space,alloc-samples) must stay consistent across 3.14 and 3.15.Summary

Intentional FAIL (current):
