build(infrahub): update file paths to match new directory structure

Refactor the .infrahub.yml configuration file to prefix all schema, menu, and object paths with the 'infrahub/' directory. This change aligns the configuration with the reorganized project structure where Infrahub resources have been moved into a dedicated subfolder.
