Docker permissions fix:

- Add user directive to docker-compose.yml using PUID/PGID env vars
- Allows container to run as host user, fixing permission issues with
  bind-mounted volumes (e.g., ./virtual_printer)
- Add chmod 777 to /app/data and /app/logs in Dockerfile for non-root compatibility
- Usage: PUID=$(id -u) PGID=$(id -g) docker compose up -d

Note: Existing named volumes (bambuddy_logs, bambuddy_data) created by previous
root containers may need to be removed or have permissions fixed manually.
