refactor(architect/llm.nix): simplify and clean up configuration

- Removed unused frontend domain, port, and listen address variables
- Centralized `ollamaHost` and `ollamaPort` usage
- Cleaned up commented-out sections for future reference or removal
- Ensured consistent placement of `acceleration` in the `services.ollama` block
