Remove deprecated scripts and add Talos schema mappings
- Deleted the following scripts as they are no longer needed:
- create-installer-image.sh
- detect-node-hardware.sh
- generate-machine-configs.sh
- Added a new file `talos-schemas.yaml` to maintain mappings of Talos versions to their corresponding schematic IDs for wild-cloud deployments.
- Updated the README in the home scaffold to simplify the initial setup instructions.
- Refactor dnsmasq configuration and scripts for improved variable handling and clarity
- Updated dnsmasq configuration files to use direct variable references instead of data source functions for better readability.
- Modified setup scripts to ensure they are run from the correct environment and directory, checking for the WC_HOME variable.
- Changed paths in README and scripts to reflect the new directory structure.
- Enhanced error handling in setup scripts to provide clearer guidance on required configurations.
- Adjusted kernel and initramfs URLs in boot.ipxe to use the updated variable references.
