refactor(hwaccel): complete migration for all GPU apps

Migrated remaining GPU apps to setup_hwaccel:
- fileflows-install.sh
- openwebui-install.sh (added setup_hwaccel - was missing)
- tunarr-install.sh

Also fixed tools/pve/hw-acceleration.sh:
- Added error handling for /dev/dri operations
- Added chmod 660 /dev/dri/* that was missing
- Added error suppression for adduser commands

All 13 GPU apps (var_gpu=yes) now use centralized setup_hwaccel:
jellyfin, plex, emby, ersatztv, frigate, tdarr, unmanic,
channels, ollama, immich, fileflows, openwebui, tunarr
