Settle on v1 setup method. Test run completed successfully from bootstrap to service setup.

- 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.
