refactor: migrate OPL2212-2 config to Attm-M4-Max and update references

- Rename host OPL2212-2 to Attm-M4-Max across codebase and docs
- Update flake.nix and README.org to use Attm-M4-Max
- Remove redundant gh program settings for simplified configuration
- Add new hosts/Attm-M4-Max/default.nix for Mac M4 Max setup
