test: fix templates paths, CLI gating, and stress-suite harness
- tests/**: update templates/ → decnet/templates/ paths after module move - tests/mysql_spinup.sh: use root:root and asyncmy driver - tests/test_auto_spawn.py: patch decnet.cli.utils._pid_dir (package split) - tests/test_cli.py: set DECNET_MODE=master in api-command tests - tests/stress/conftest.py: run locust out-of-process via its CLI + CSV stats shim to avoid urllib3 RecursionError from late gevent monkey-patch; raise uvicorn startup timeout to 60s, accept 401 from auth-gated health, strip inherited DECNET_* env, surface stderr on 0-request runs - tests/stress/test_stress.py: loosen baseline thresholds to match hw
