Drop the two-subdomain split (ADR 0004): report at /, view defects at
/defects, with a shared layout + header nav. Renames the dashboard page to
defects.vue and updates plan/README. Transparency over separation now that
auth gates everyone, and it removes the Coolify two-domain routing question.
Nuxt 4 (app/ structure) + TypeScript, ESLint, Vitest + @nuxt/test-utils,
Drizzle + pg, a /api/health route with a DB ping, and a dev docker-compose
(app + Postgres). Verified: pnpm test, lint, and build pass; the built
server answers /api/health.
