chore: move zola infrastructure to deprecated/

Relocate legacy static site generator configuration to clear
namespace for new Rust-based compiler:

- config.toml, netlify.toml
- sass/, templates/ directories
- themes/apollo submodule (updated .gitmodules path)

Content directory preserved at root for compatibility.
