feat(ansible): add Docker host configuration with NFS mounts and utility packages

- Introduce Docker host configuration playbooks in `docker_host` role
  - Install Docker and Docker Compose via apt repository
  - Configure Docker user, group, and required directories (`/opt/docker`, `/media`)
  - Add NFS mounts for Docker data, series, movies, and songs directories
- Add extra utility packages (`bat`, `ripgrep`, `fd-find`, `screen`, `eza`, `neovim`)
- Set up and manage `bash_aliases` for user-friendly command replacements (`batcat`, `nvim`, `eza`)
- Enhance `/group_vars` and `/host_vars` for Docker-related settings and secure access
- Add `docker-host00` and `docker-host01` entries to production and staging inventories
