tools: Centralize GPU group setup via setup_hwaccel (#13044)

improve hardware-acceleration setup to centralize service user group management. Install scripts (emby, plex, ollama, channels) now pass a service user to setup_hwaccel (or no user for channels) and have had inline /etc/group sed/usermod tweaks removed. misc/tools.func updated: setup_hwaccel accepts an optional service_user and forwards it to _setup_gpu_permissions, which now adds the service user to render and video groups if provided. This consolidates GPU permission changes in one place and removes duplicated per-service group edits.
