chore: remove all NestJS backend references, replace with Hono/Bun

- Delete nestjs-backend.md guideline (replaced by hono-server.md)
- Delete Dockerfile.nestjs-base and Dockerfile.nestjs templates
- Delete stale BACKEND_ARCHITECTURE.md doc (NestJS-era, obsolete)
- Update CLAUDE.md, GUIDELINES.md, authentication.md to Hono/Bun first
- Update all app CLAUDE.md files: backend/ → server/, NestJS → Hono+Bun
- Update all app package.json files: @*/backend → @*/server
- Update docs: LOCAL_DEVELOPMENT, PORT_SCHEMA, ENVIRONMENT_VARIABLES,
  DATABASE_MIGRATIONS, MAC_MINI_SERVER, PROJECT_OVERVIEW
- Update scripts: generate-env.mjs, setup-databases.sh, build-app.sh
- Update CI/CD: cd-macmini.yml backend → server paths
- Update Astro docs site: @chat/backend → @chat/server
