feat(ci): track time.sleep in docker test profiler

The profiler now monkey-patches time.sleep alongside subprocess.run,
capturing the invisible "gap" time from polling loops (wait_for_container_ready,
poll_container, wait_for_log, etc.) that was previously unaccounted for.

The JSON report now includes per-test total_sleep_s, sleep_count, and
a sleeps[] array with caller location. The summary includes
total_sleep_s and total_wall_s (docker + sleep). The CI merge step
also aggregates sleep totals.

Local profile now shows: 201s docker + 75s sleep = 276s wall (38s
runner wall with 32-way parallelism). The biggest sleep consumer is
test_dashboard_insecure_env_var_no_longer_bypasses at 11.8s of
poll_container sleeps.
