Breaks out wild-setup phases into independently-runnable scripts.

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.
