Add dnsmasq and Talos setup documentation and configuration files
- Created `dnsmasq-setup.md` guide for setting up dnsmasq on hardware like Orange Pi Zero 3. - Added `talos-setup.md` guide for an alternate setup using Talos and bare Kubernetes. - Introduced configuration files for dnsmasq including `.not_logged_in_yet`, `bare-metal.yaml`, `boot.ipxe`, `dnsmasq.conf`, and `nginx.conf`. - Implemented `setup.sh` script for automating the installation and configuration of dnsmasq and nginx. - Updated example configuration in `config.example.yaml` to include Talos versioning. - Modified README to reflect changes in Wild-Cloud app commands.
