feat(web): Split code between beta and classic

[KaWaite]

Overview

See the design doc for details.
Tl;dr splitting the code up in preparation for developing Re:Earth's new design that harnesses the New Layer System.

What I've done

• Moved classic specific code in to the classic directory. Setup the beta directory structure.
• The original plan was to have services in beta, but state, graphql, etc are shared services (and won't change much) so I preemptively moved it to src.
  Additional:
• Installed rollup directly to get rid of an error in the vite.config file around the yaml plugin
• Fixed husky's pre-commit issue when moving gql directory by making the lint-staged path web/xxxx, not xxxx
