Enhance dnsmasq setup with new scripts and documentation

- Add custom dictionary words for spell checking.
- Refactor wild-central-generate-setup script for improved error handling and structure.
- Create README.md for central dnsmasq setup with detailed instructions.
- Implement create-setup-bundle.sh and setup.sh scripts for setting up dnsmasq and PXE booting.
- Add transfer-setup-bundle.sh for transferring setup files to the server.
- Update SETUP.md with clearer instructions for initial setup and configuration.
- Introduce .gitignore for dnsmasq setup bundle.
