chore: overhaul infrastructure and integrate @mintel packages

- Restructure to pnpm monorepo (site moved to apps/web)
- Integrate @mintel/tsconfig, @mintel/eslint-config, @mintel/husky-config
- Implement Docker service architecture (Varnish, Directus, Gatekeeper)
- Setup environment-aware Gitea Actions deployment
