Pull Request Overview

This PR refactors the contracts file tree by consolidating interface and facet contracts into more organized directories. It moves from a modules/ structure to direct interfaces/ and facets/ directories, and removes outdated interface files that are now relocated.

• Move interface contracts from modules/interfaces/ to interfaces/
• Move facet contracts from modules/facets/ to facets/
• Update import paths throughout the codebase to reflect the new directory structure
