Auto-commit: v2.10 — Docker/compose hardening for Portainer on Pi

docker-compose.yml:
- Add PYTHONIOENCODING=utf-8 env var (guarantees UTF-8 stdout in all
  Python environments, including Docker slim images on ARM).
- Add logging driver section: json-file, max-size 10m, max-file 5.
  Without this the json-file log on a Raspberry Pi SD card grows
  unbounded and eventually kills the container or fills the disk.

web/requirements_web.txt:
- Pin huey==2.6.0 so a future pip upgrade cannot silently change the
  Consumer() API and re-introduce the loglevel= TypeError that caused
  all tasks to stay queued forever.
