[CI] Fix test_mixed_warmup_gate after #57053

[MatthewBonanni]

Purpose

tests/v1/worker/test_mixed_warmup_gate.py::test_mixed_warmup_disables_watermarking fails on main, breaking the "V1 Executor + Worker" step (H200 MIG 18GB and MI355 DPX) for every PR:

vllm/v1/worker/gpu/warmup.py:150: AttributeError: 'types.SimpleNamespace' object has no attribute 'num_speculative_steps'

#56801 added this test with a fake runner; #57053, merged 17 minutes later, made the warmup read model_runner.num_speculative_steps. Main build 92930 (#56801) passes the test; 92932 (#57053) fails it on both platforms.

Fix: give the fake runner num_speculative_steps=0.

Test Plan

pytest tests/v1/worker/test_mixed_warmup_gate.py

Test Result

On main (74c5cbcd7b): 1 failed, 4 passed. With this PR: 5 passed (macOS, CPU).

CI selector (shadow): 1 test steps (1 jobs) instead of 7 (10 jobs)

Shadow mode: this changes nothing about what CI runs. It shows what the evidence-based selector would pick for this PR, next to today's rules. How it works.

Feedback welcome: reply here if it would skip a step this change needs, or runs something unrelated.
